Thanks, Zilli, and thanks to everyone for joining us today. Klaviyo delivered very strong results in the second quarter, with revenue of $222 million, growing 35% year-over-year. We believe we are a must-have platform for more than 151,000 customers around the world as we help them easily and quickly transform their data into more valuable connections across every touchpoint. Our customers are at the heart of everything we do. We work to earn their trust every day, and our model is built for joint success. So as our customers grow, Klaviyo grows. We power smarter digital relationships. Our vertically integrated platform enables customers to use real-time, first-party data to create segments, orchestrate personalized omni-channel campaigns, and measure every interaction. Most importantly, we've made it incredibly easy. Marketers no longer have to hire a developer to build and manage an API to connect to a new data source or write code to create a consumer segment. With Klaviyo, complex tasks are made simple, allowing marketers to be more efficient and focus more time on their consumer engagement. From entrepreneurs just starting their businesses to established, internationally known brands, Klaviyo is a revenue engine for our customers. Our unified platform across the data and marketing layer, our omni-channel orchestration, our fast, flexible functionality, and our more than 350 integrations drive companies to choose Klaviyo. Then they stay and grow with us, adding products like SMS, CDP, and reviews, and take advantage of our new AI features and advanced analytics across their entire consumer data set. As customers leverage all of these tools, we can show the actual value of our platform is driving with Klaviyo Attributed Value, or KAV, which measures the revenue generated through consumer transactions after engagement with any of our channels. When customers sign in to Klaviyo, KAV is one of the first things they see, so they know how much revenue our platform is driving for them. Our ease of use and the direct correlation to revenue is a key reason why companies choose Klaviyo. A great example is our new relationship with a Fortune 1000 global company. They wanted to build out their direct-to-consumer offerings, engaging consumers with new content. They were previously using a legacy platform, but selected Klaviyo for our ease of use and the ability to integrate their data across all their core marketing channels. They also selected our SMS solution, a channel they'll be using for the very first time, to execute their omni-channel strategy to fuel additional revenue growth. We also closed a deal with a multi-billion dollar revenue national chain of grocery stores. They were using a homegrown solution to batch and blast communications. Each email had to be created from scratch, and they couldn't do any segmentation. The CIO demoed Klaviyo and quickly realized the team would see big productivity gains from our out-of-the-box segmentation, data orchestration, and the flexibility of our campaign and flow creation. Companies of all sizes are building omni-channel marketing strategies using email, SMS, and push notifications to build personalized consumer relationships. But many use multiple point solutions, leaving them with disjointed consumer data, an incomplete view of their consumers, and a fragmented communication experience. If you've ever received an email from a brand asking you to review a product that you returned weeks ago, then you've seen this breakdown in action. That's why we've integrated all of those channels on one platform, ingesting data from every touchpoint and giving our customers powerful insights that enable them to execute a differentiated omni-channel strategy. Samsonite, the world's largest travel luggage company, chose Klaviyo this quarter because we could bring all of their data into one place. Samsonite was using multiple point solutions for email and SMS. They had fragmented data, and after eight years with their email provider, they had only built four automated workflows due to the difficulty of customizing the solution. They were impressed with the number of easy-to-build options that Klaviyo provides across our templates, forms, and flows.... Samsonite selected Klaviyo over a large legacy provider to unify all seven of their North American brands, bringing email and SMS together onto our platform. SMS continues to be a key driver of growth for us as companies look to consolidate SMS capabilities with Klaviyo to better leverage our data platform for multi-channel flows and campaigns. This quarter, we expanded our relationship with Barstool Sports, the sports digital media company, with over 65 content franchises and 198 million social followers. They've been a Klaviyo email customer for 8 years and have seen tremendous success selling their merchandise and expanding their influence in the sports and entertainment communities. As their contract with a point solution SMS provider came to an end, they opted to consolidate with Klaviyo, so that all of their consumer data will be housed on our platform, allowing them to better segment and orchestrate the data for more personalized communications across channels. We also started a new relationship with Boston Proper, a legacy fashion and apparel brand that historically has relied on selling via catalogs. The company's technology infrastructure was fragmented, hindering its ability to provide a seamless and personalized shopping experience for its consumers. They chose to consolidate from multiple point solutions to Klaviyo, centralizing all online and offline consumer data into our data platform. Boston Proper is leveraging our email, SMS, and CDP solutions to build stronger relationships and to help grow their top line. The more first-party consumer data you have on one platform, the stronger your campaigns will be. With help from our growing ecosystem, we built out an incredible third-party integration library, so our customers can pull in their data from anywhere. These integrations are both inbound and outbound, allowing customers to bring all of their data onto our platform, as well as leverage Klaviyo data on other platforms like Google and Meta. This quarter, we added Toast and Bazaarvoice, new inbound integrations, and TikTok and Pinterest, outbound integrations, which allow customers to connect their Klaviyo profiles to the ad audiences, improving return on ad spend. We also announced a new integration framework that significantly reduces time to build on Klaviyo by up to 43%. We plan to open up this framework to third-party developers in the future to enable them to create both inbound and outbound integrations with Klaviyo more efficiently. Herschel Supply Co., a global travel lifestyle brand, chose Klaviyo in Q2, in part, because of our third-party integrations. They were frustrated with their prior point solution due to lack of innovation, poor integration, and reporting challenges. Following a competitive RFP process across point solutions and legacy providers, they chose Klaviyo because they felt that our massive integration library and functionality and AI features would give them the right edge for growth. Speaking to AI, we continue to enhance our AI suite. As I've mentioned previously, we think about AI three ways: productivity, optimization, and creation of new marketing strategies. Marketers need artificial intelligence to be practical, effective, and easy to use. But AI is only as good as the underlying data. Because our platform can ingest up to the second first-party consumer data, Klaviyo can provide more accurate benchmarks and drive actionable insights through our artificial intelligence tools. A few weeks ago, we announced several new features. Flows AI allows marketers to build a flow in seconds with a simple prompt and ultimately drive more revenue. Personalized Campaigns take A/B testing to the next level by determining the winning version of a campaign for each individual subscriber based on their likelihood to engage. Review Sentiment AI quickly analyzes product reviews at scale, so brands can get insights and take action faster than ever. We also want our AI features to easily provide guidance, so we recently introduced a feature that gives recommended actions and tailored next steps, powered by artificial intelligence, as soon as customers log into their Klaviyo homepage. Our customers are increasingly adopting our AI products, as we've seen a 61% increase in accounts using one of our generative AI features. We're excited by Klaviyo AI's ability to help marketers move beyond what was previously possible, unlocking new growth strategies. As a customer-first organization, we are focused on investing in areas that will help us support our customers and make them more successful across sales, product, and support. We've been investing in our go-to-market efforts over the last few quarters with a focus on growing our sales capacity to address mid-market and international opportunities. Additionally, we continue to invest in training for new sales hires and expanding our partner ecosystem to ensure we have the right agencies, system integrators, and technology partners to help our customers succeed. Internationally, we are investing to expand our presence and platform offering. During the quarter, we continued to enhance our localization and internationalization with the expansion of our SMS capabilities into Austria, Switzerland, and Spain, as well as adding MMS in Australia. We now provide SMS coverage in 12 countries, more than double the 5 countries we had coverage for this time last year, and we plan to continue to expand our international footprint going forward. This quarter, we launched our product in French, and we saw a large increase in new customers and usage as a result. For example, we signed a new deal with Le Petit Ballon, a French wine subscription company. They were looking for a new solution to help them generate more revenue through email and to improve overall consumer retention. They chose Klaviyo because of our data platform and plan to start testing SMS in addition to their use of email. We are dedicated to continually improving our platform and product offering for our customers. Customers tell us that our product roadmap is a key differentiator. In Q2, we released a number of new features, including a bulk profile suppression tool, which helps our customers keep their active profiles clean by suppressing profiles that may have stopped engaging with their brands. Companies can now suppress those profiles with one click, so they can market to the right consumer and ensure good deliverability. Today, we also released Reputation Repair AI, which will determine when an account has poor deliverability, identify and segment out those accounts to create a clean list, and ensure brands are sending to the highest quality profiles, leading to stronger deliverability and email performance. Deliverability is hugely important. You may have the best content in the world, but it only works if it gets delivered. We've been investing heavily in our deliverability infrastructure and systems, and I want to thank our team, who is focused day and night on ensuring the highest quality, deliverability, and sender reputations. Equally important is compliance, and our team is focused on preventing abuse of these channels, whether malicious or accidental. We're able to maintain strong compliance because we have insight into an enormous amount of data that allows us to see what's going on and how to stop it. As a result of these efforts, we've navigated the changes from the email service providers extremely well, and we're seeing the benefits from those efforts as companies turn to Klaviyo after negative experiences with other providers. A great example of this is Olive & June, a leading provider of at-home manicure and pedicure products. They were using a lower-cost provider but were facing severe deliverability issues. They came to Klaviyo because of our strong reputation in the market, the power of our platform, our deliverability strength, and our integrations with their other systems that will help them build better relationships with their end consumers. As we continue to add more features and functionality to the platform, we are committed to empowering our customers to get the most out of Klaviyo by making it easy to find answers about best practices, partners to work with, and a community to engage with. To provide excellent customer support across all segments, we recently launched Klaviyo Power Up, our new centralized customer resource center, designed to bring all of these assets together in one place. Power Up will help customers easily discover self-service resources and deliver curated content throughout their journey with Klaviyo. We will continue to enhance Power Up as part of our dedication to support our customers' long-term success. I'm extremely happy with our second quarter results and the strong first half of the year. We have a tremendous long-term opportunity ahead of us as we help our customers power smarter digital relationships around the world, and we have even bigger plans for the future to unlock use cases beyond marketing for our customers. Before I hand it over to Amanda, I'm very proud to announce that Klaviyo was named an Inc. Best Workplace for the sixth year in a row, and Newsweek listed us as one of America's Greatest Workplaces for 2024. Thanks to all the Klaviyos for keeping up the energy of our culture. And with that, I'll turn it over to Amanda. Thanks, Andrew. Klaviyo delivered another quarter of strong financial performance in Q2 as we continue to drive efficient growth at scale. Revenue grew 35% year-over-year to $222 million, and we reported a 15% non-GAAP operating margin, both exceeding our expectations. We're very pleased to deliver well above the rule of 40 with this performance. We continued to deliver across our four primary growth vectors: adding new customers, expanding with those customers, expanding internationally, and growing in the mid-market. In Q2, we added over 5,000 new customers and now have more than 151,000 customers, up 16% year-over-year. We saw strength in entrepreneurs and in the high end of the market. However, we are seeing some of the softness in the SMB market that has been widely discussed across the industry over the last several months. Despite this, we delivered a strong quarter due to the diversity of our customer base across customer size and geography. Existing customers continue to expand with us by growing their existing usage and adding new products, as can be seen in our dollar-based net revenue retention rate, or NRR, which was 112% for the quarter, an expected decline due to the lapping of our September 2022 price increase, as well as the customer trends we spoke about earlier this year. We continue hearing from customers about macro pressures, and they remain focused on the value they're deriving from their software. As a result, our expectations for a continued decline in NRR in the near term haven't changed. It's important to note that despite this, we continue to see strength and stability in our gross retention rates, which confirms our belief that Klaviyo is a must-have platform for our customers. Internationally, we continue to grow our global business. You'll recall that we announced the launch of our French language product in Q2, and we have seen extremely strong trends there as a result. France was our fastest-growing country in new business in the quarter, up more than 65% Q1. We also saw strength in the U.K., Ireland, Italy, and Germany. In fact, our year-over-year revenue growth in EMEA accelerated to 45% in Q2 from 43% in Q1. In aggregate, our international revenue grew 41% year-over-year. Finally, the go-to-market initiatives we implemented last year are delivering great results. At the end of Q2, we had 2,386 customers generating over $50,000 in ARR, which was up 64% year-over-year. We're also seeing a healthy trend of landing new customers in this cohort from the start, adding the largest quarterly number in our history, evidence that our strategy is working and of the growing importance of our platform to our customers. Non-GAAP gross profit for the quarter was $175 million, representing a non-GAAP gross margin of 79%, up 140 basis points year-over-year. This came in slightly better than expected as we continue to absorb mix shift pressure from our growing SMS business through operational efficiencies across our infrastructure and support organizations. For the full year, we expect non-GAAP gross margin to be down slightly from last year. Turning to non-GAAP operating expenses. Sales and marketing expense was 32% of revenue for the quarter, up 140 basis points over last year as a result of our investments in sales, headcount, and marketing programs that we've discussed the last few quarters. R&D expense was 19% of revenue, down 100 basis points year over year, primarily driven by an increase in capitalized software as a result of more development work on customer-facing features that we'll be rolling out. Finally, G&A expense was 13% of revenue, down 170 basis points year over year, primarily as the result of the release of some international tax-related reserves. We do expect more of these releases over the next few quarters, which may drive some fluctuation in G&A expenses. For the second quarter, our non-GAAP operating income was $34 million, representing a non-GAAP operating margin of 15%. This was stronger than our guidance as a result of the revenue strength, the items I discussed earlier, as well as headcount coming in a bit lighter than expected for the quarter. We generated free cash flow of $37 million during the quarter, down slightly from the prior year due to payroll and other operational expenses, as well as the timing of collections. Moving to guidance. For the third quarter, we expect revenue to be $225 million-$227 million, representing growth of 28%-29% year over year. We expect non-GAAP operating income to be $21.5 million-$24.5 million, representing non-GAAP operating margin of 10%-11%. This is a bit better than we had suggested last quarter, due to a shift in the timing of some investments, as well as the lower OpEx related to slower than anticipated headcount growth in Q2. For the third quarter, we expect fully diluted shares outstanding to be approximately 300 million. For the full year, we are increasing our revenue guidance by $11 million- $910 million-$918 million, representing growth of 30%-31% year-over-year. We are also raising our non-GAAP operating income guidance by $6 million to $103 million-$111 million, representing a non-GAAP operating margin of 11%-12%. We continue to make incremental investments across go-to-market and product opportunistically, and expect those investments to be spread across Q3 and Q4 as we set Klaviyo up for long-term growth. Finally, for the full year, we expect fully diluted share count to be approximately 301 million. In closing, these strong results are a clear indication that Klaviyo's platform is driving success for our customers. We are excited about the remainder of 2024 and the coming years as we continue to build the foundation for durable and efficient growth going forward. And with that, we'll open up the call for Q&A. Operator? We are now opening the floor for a question and answer session. If you'd like to ask a question, please press star one. We do want to incorporate as many analysts as possible on the call, so please limit one question before returning to the queue. Our first question comes from Brent Bracelin from Piper Sandler. Your line is now open. Thank you. Good afternoon. I guess I wanted to start out here with the durability of growth. Clearly, the macro is pretty challenged out there, remains challenging for many, but looks like growth for you is actually stronger this June quarter than it was a year ago. Growth accelerated a little bit on top line. You're guiding up for the year. Can you just double-click into the demand drivers that's giving you optimism and underpinning this, the strength here? It is surprising and just love to hear a little bit more around what's driving the optimism in the business and the momentum. Thanks. Yeah. Thanks, Brent. It's Amanda. Appreciate the question, and we're very pleased with the results from the quarter. You know, it was a really strong revenue quarter in Q2. As we talked about on the call, we saw strength in the entrepreneur side of the market, driven by efficiency from our marketing investments, as well as some investments we've made in product to increase our free-to-paid conversion. We saw strength in the upper end of the market, and we added this quarter, as we said, our highest number of greater than 50K ARR customers that we have in our company's history. And then we also continue to see strength in SMS. We're expanding our penetration and our usage with customers, and we're seeing strong growth internationally. International had a terrific quarter, growing 41% year-over-year. Really, you know, multiple drivers of the strength in the quarter, and I think what it is a testament to is the diversity of our customer base across customer size, across geography, that shows that we can be durable and resilient across multiple operating environments. Helpful color. Thank you. Our next question comes from Keith Weiss, from Morgan Stanley. Your line is now open. Hi, So. Thank you guys for taking the question, and congratulations on a really solid quarter in a really uneven macro backdrop, if you will. I wanted to focus maybe one question on the top line, one question on the bottom line. On the top line, new customer adds were definitely highlighted. Picked up a lot from last quarter. What's enabling that? Like, is it some of the, like, partner initiatives? Is it the expansion of products into international companies? Can you give us a little bit of color on, what's enabling you to sort of pick up that customer adds, even with the, with the weaker SMBs and the weaker backdrop? And then on the, like, the bottom line side of the equation, really good operating margin performance this quarter. But it does seem like our Q4 numbers are coming down a lot if we take the Q3 guide and the Q and the full year guide. Anything in particular that's going to be pulling down that Q4 or any, like, different timing in investments or ramp-up in investments that explains that? Thank you. Sure. Thanks so much, Keith, and appreciate your kind words. It was a strong quarter for net adds. We added 5,000 net new customers in Q2, and now we've got over 151,000 customers. As we talked about last quarter, increasingly, we are shifting our go-to-market resources towards SMB and mid-market. In the enterprise group, we're putting more into product-led growth, and this quarter, we saw the benefit of those efforts. We saw strength in that enterprise customer group that was really driven by efficiency from our direct marketing spend, as well as improvements in free-to-paid conversion coming from our product-led growth efforts. We talked a little bit just a minute ago about the strength that we saw at the upper end of the market as well, and that is as a result of the go-to-market investments that we've been making to really, you know, drive that, that strength in those larger customer lands as well. Now, I will say on the net ads, keep in mind, that is a number that might move around a bit over time. We're okay with that because our focus is really on adding high-quality customers. We're really pleased this quarter that we added customers like Samsonite, Boston Proper, the Fortune 1000 company Andrew spoke about, and the national grocery retailer, and we're looking forward over time to helping even more customers grow. And then, regarding your question on investments and the timing of investments and how those may unfold during the year, you know, as we spoke about at the beginning of the year, as we are going through the year and, you know, see outperformance in the business, we're gonna be reinvesting that back to continue to drive durable growth. We're reinvesting it incrementally, across go-to-market and product. And two of the areas of focus for investment for us are mid-market and international. Those investments are ongoing. We're continuing to build out the right team, the right infrastructure to capture those markets. And importantly, we're seeing strong returns. As we talked about on the call, international investments are leading to really strong growth in EMEA and APAC. As we look towards the back half of the year, we're gonna be increasing our marketing efforts in the run-up to Black Friday, Cyber Monday, and we're continuing to invest in our product team, to enhance existing features, to launch new features. Some great examples of that this quarter were the new features that we launched, AI, that we announced recently. So as always, you know, as we make those investments, we're doing it with a really clear eye and a focus on unit economics to make sure that we're getting good, returns to continue to drive that efficient growth in the future. Outstanding. Super helpful. Thank you, guys. Our next question comes from Siti Panigrahi from Mizuho. Your line is now open. Thanks for taking my question, and congratulation on a strong quarter. My question about your new products. You guys talked about AI, even some of the integration as well, and reviews, some of that don't have the direct pricing. How do you monetize that to your base? And then as you are seeing large customers using your product, how does that influence your product strategy? How should we think about those upcoming products in next few years? Sure, happy to dive into that. So if you think about the products that we've released, you know, we started out with our core, you know, database and email products. We added on SMS, and in the last year, we've added both Reviews and CDP, and those are both products that we're monetizing directly. And we're seeing good adoption there. Very excited about the progress we're making with both of those. And then on the artificial intelligence, the AI side, you know, one of the things we think about is AI in these three different use cases: productivity, optimization, and expanding your marketing strategy. So for artificial intelligence, the productivity tools we're building, we expect that those will... We're not monetizing that directly, but those do drive incremental usage, so there's an indirect mechanism there. And then for a lot of the stuff we're doing around helping you optimize marketing campaigns, figure out the right content, the right timing, tuning to who receives which message, as well as generating net new strategies... what products that customers often buy together, helping you come up with new marketing ideas. Those we think are going to be incremental to Klaviyo attributed value or the revenue that we help our customers create. And while we're not monetizing those today, we do think that there's an opportunity to monetize those over time. And what's great about them is they're not just for productivity. They really are—they're directly revenue driving, so our customers really understand the value of those. So we're working with a lot of customers on building that, the functionality out. We don't have any timelines right now to monetize those, but we, we know there's an opportunity. And lastly, you talked about, you know, product strategy. How does—as we drive more adoption, we have more customers that are multi-product. How do, how do we think about that? You know, at the core of Klaviyo is the, is the data platform that we built, the single, source of truth for everything you need to know about your consumers. We want to help every business take advantage of that and use it so that for every interaction that the consumers have with that business, that it's personalized, that they can measure how much customers like it, and then they can use artificial intelligence to optimize it. And we think we can take that well beyond just marketing and channels, but we can take that to other customer services. When you think about things like what it means when somebody's trying to get educated or they have a question, or to digital properties, like people's websites and mobile apps. So I think you'll see from us, you know, the use cases, and therefore the products that can expand often on top of this data platform we've built. There's a lot of those, and I'm very excited about the building we're going to do on that over the coming months and over the coming years. Thanks for the call. Our next question comes from DJ Hynes, from Canaccord. Your line is now open. Hey, guys. Congrats on a really nice quarter, and thanks for taking the question. So Shopify obviously reported this morning, I'm sure you saw that, really strong merchant ads. Interestingly, they said about half of their new merchant ads in Q2 came from outside of core English-speaking markets. So two questions there: A, do you see the same demand characteristics in those markets? And then, B, how quickly can you guys move to localize the platform for those merchants? Yeah, I'll start to give a little color on international, and Amanda can follow on. So, I think we're seeing strong international growth as well. So we mentioned, you know, earlier this year, in the last few months, we launched our product in French, you know, along with local language marketing, and that's gone very well. And I think that we can take that playbook that we've run in France and take that to other languages, and then other markets. And so you can see we've had some great wins there, like with companies like Le Petit Ballon. And more broadly internationally, I think we're starting to invest in plays to look like, you know, the documentation, the customer stories. Also, we're localizing now some of the digital marketing ad campaigns we're running. So I think you'll see those play out, you know, over the coming months. Thank you. Our next question comes from Arjun Bhatia, from William Blair. Your line is now open. Perfect. Thank you, and I'll add my congrats on a nice quarter here. Andrew, maybe one for you. Just one of the things that we didn't touch on as far as your push, mobile push capabilities, I'm curious how progress is going there. And when you think about some of these upmarket, some of the top market momentum that we're seeing, especially with new customers landing in that 50K cohort, how much is that the mobile capabilities contributing to it, where customers might be buying all of your channels up upfront as they look for a platform that they can scale on? Yeah, absolutely. So I think when we start to reach into the mid-market and the enterprise, I think folks, again, are coming to us primarily for our data platform and then all of the marketing channels in one place, and it's that tight integration. So specifically on mobile, I think we talked about on the last call, we now have several customers that are sending high volume number of push notifications and using other mobile functionality. We obviously have a good chunk of our product team that's working on building out those capabilities. And what we're finding is, similar with email and SMS, folks are interested in how, you know, the interplay between those channels, and they want all of them in one place. They want great content creation tools. They want to use the data that Klaviyo provides to help personalize and measure the performance of each of those campaigns. So I think it's early for us. We're finding customers where, you know, that was a requirement for them. Now we're able to address that, and I expect over time, you know, we see in enterprise, there's a mix of folks that either have mobile, you know, mobile properties where they need that functionality, and then those that don't. I think we're finding that we can now address those, and, you know, within retail and e-commerce, there's obviously folks that have mobile apps, but then even outside of that, that's opening up new use cases for us that we can start to address. So I think, you know, over the coming couple of quarters, you know, we're making more investments there. All this idea of any way you want to communicate with your customers, with your end consumers, you can do that with our products. All right, perfect. Thank you. Our next question comes from Derrick Wood, from TD Cowen. Your line is now open. Oh, great, thanks. Congrats on a great quarter. Andrew, there seems to be talk that the AI wave is starting to drive more companies to invest in personalization in the marketing and customer engagement space, and certainly that sounds like what you're seeing with talking about AI driving new marketing strategies. But you know, given that you've got this vertically oriented stack with a rich data layer to really help with personalization, how are you seeing... How would you characterize demand and competitive positioning for Klaviyo today versus a few quarters ago, now that there's been a lot more focus on AI-related initiatives? Yeah, so I'll say two things. I mean, the first is the importance of having, allowing businesses to take, use the data asset, you know, the consumer data they have, the things they know about their end consumers, and put that to work, and have that so tightly coupled with the, you know, applications where you actually take action on it. So marketing is one. That integration between database and, you know, system of action is really important. So I think we're actually, we've got a big, like, heads-up, you know, bit of a lead on that. And then you can start to see that with some of the features that we're building. So for example, like we talked about, productivity as a use case. We've now released Email AI, Segments AI. This past quarter, we launched Flows AI. All of these are tools so that whether you're, you know, a small business, an entrepreneur just starting out or a large enterprise, you can build more marketing campaigns faster. And actually, those prompts can look into your data set and understand the kind of data you have, to automatically create different segmentations or workflows for you. So on the productivity front, we're making a lot of progress. We're also able to release personalized campaigns. And so if you think about what that feature is all about, it's this idea of if you have multiple variations of a campaign, for some businesses, it could be dozens. You know, historically, what that meant was you just pick the best version for everybody. What we're actually able to do, because we have all the data inside of our data platform, we can actually figure out on a consumer-level basis for each person, what's the right content for them? And there's incremental lift on that. So I think all of this is, you know, the thesis that we've had of help people pull all their data together, then allow them to action it. I think with artificial intelligence and machine learning, we're now able to help them accelerate actually doing that. And what I'm excited about is our ability to now, you know, suggest strategies, more optimizations, and folks to allow businesses to do that more autonomously. So I, you know, we feel really good about where we are, and we are very much full speed ahead on bringing this to life. Because I think, again, this is not just productivity for us, this is about driving incremental revenue, and that's even more important for these businesses. And that really is- Great, thank you. Building a... It's important for customers of all sizes, and we're absolutely seeing it come through in why customers are coming to us. We had a win this quarter with a provider of spa-inspired hair products, and they were working with a legacy cloud provider. They wanted to be able to have really strong customer engagement, but what they were seeing was poor open rates, ineffective segmentation, lack of insights. All of those brought them to Klaviyo, and they consolidated their email, their SMS, their CDP, and Reviews with us. And now we're excited to work together so that they can use our platform and their customer data to really help drive that personalization and revenue growth. Awesome. Thank you. Our next question comes from Terry Tillman from Truist. Your line is now open. Yeah, thanks for taking my question. I guess I should say bonjour, with the ramp you're seeing in the French market. It's a single question. It's got two parts, though. First, I know you all have been evolving and kind of testing and learning with CDP, but what are you seeing after you've done some kind of price packaging updates? Is that helping incrementally with adoption? And then the second part of this question is, I heard a lot in your all's prepared remarks around deliverability. As you're getting more of these kind of bigger customers in initially, and kind of this world around TCO and maybe with bulk sender changes, is deliverability creating kind of a new almost replacement cycle? Thank you. Hey, great. Thanks, Terry. So first I'll talk about CDP. So what we found with our customer data platform, our CDP product, there's really two core use cases. The first is storing all that data, creating a system of record, governing it, data hygiene. So that's part one, and then part two is allowing folks to do analytics on top of it, to figure out which customer segments they, you know, they should be marketing to. So what we've actually started to experiment a little bit with is different ways to think about packaging that. Do you put both of those together? Do you separate those out? And I'm really excited about both the progress we're making on the product side. On the data tooling side, we've done a lot of work to improve, you know, both the speed of ingesting data as well as getting it out to other systems. We talked about at the top of the call about how outbound connectors are a big part of the integrations to Klaviyo and speeding that up as well. And then on the analytics side, you know, as an example, we launched a new feature within the CDP around product analytics. So we can actually help brands with lots of SKUs figure out where there's affinities between products, and they can instantly turn that into marketing campaigns that drive incremental revenue. So we're excited about the progress there. On deliverability, what I'd say is that's been at the core of, you know, it's been one of the things we've focused on since we started. It's obviously what Klaviyo stands for, personalization and getting the right person the right content. You know, as we saw some of the changes roll through email service providers, those haven't had a material impact on us. In fact, we've seen some customers come to Klaviyo. They know this is a revenue engine, they know how important deliverability is, and they've chosen us because of our dedication to email and SMS deliverability. So both our customer teams and our engineering teams have done a great job to ensure that, you know, deliverability is working for folks. So, I think on both the delivery front has become a big differentiator, and on the CDP front, we're very excited about the progress that's there. I think there's... We're starting to learn a lot about the use cases and potentially, you know, think about some, you know, some packaging changes. Our next question comes from Raimo Lenschow from Barclays. Your line is now open. Thank you. Could we, I tried to go back, I'm trying to go back to the health of the SMB, and Amanda, your comments as well. Question is, if you think about the behavior of an SMB, like- ... you know, like clearly, you know, you guys seem to be seen as more strategic for them because, you know, if you don't market, you can't sell, which basically means you can't survive. But like, how do you see the customers stacking up in terms of like, you know, fitting you in and, and seeing you as something that kind of helps them versus something that is nice to be like we see at other solutions? Just, just help us understand as well, like, you know, how that kind of slightly more uncertain SMB market is playing into your thinking. Thank you. Yeah. I'll add on top of what Amanda said a few minutes ago. So the first is, we're a must-have revenue engine for these businesses. That's what makes us so essential, and that's what we love to helping our customers do, grow their businesses. I think within the SMB, it's a little nuanced. We actually divide, you know, SMBs into two groupings. The first is entrepreneurs. You can think about businesses that are really just starting out, very small teams. And then we also think about, like, larger SMBs. So to speak to each of those two categories, you know, when we talked about some of the softness, as Amanda mentioned, we've seen relatively fewer ads in that larger SMB space. And we think part of that's attributed to slightly longer sales cycles. Now, we still find folks are moving to us, but, you know, those sales cycles are a little bit longer, and, you know, just as a reminder, we measure our sales cycles with those larger SMBs, I mean, still in days and weeks, not months. Now, for the smaller segment there, for the folks that are just more just starting out, that's where we did see a lot of strength broadly across that customer group from net new logos, and new folks that are new to Klaviyo. So I think that we think that's a really good sign that when businesses are starting out and they're looking to grow their business, they're still choosing us and defaulting to Klaviyo, as the place to store customer data, and then, you know, message those customers and ultimately, you know, grow their business. Okay, perfect. Thank you. Our next question comes from Scott Berg from Needham. Your line is now open. Hi, everyone. Really nice quarter here, I guess. One question for me is on your go-to-market and, and investments here, kind of mid-year. SMB, as Amanda pointed out, still a little on the, softer side at the moment, but you both called out really good strength up market. Have you made any tweaks or changes to the investments that you're making across those different segments that might maybe favor some of those areas of strength up market that you're seeing today? Yeah. So, yeah, we're, we're very intentional about looking for where there's opportunities, where we're seeing market pull and investing behind those. Maybe add a little bit of color, you know, on the sales side, we've been increasing capacity in the areas where we're seeing growth. Amanda mentioned international as well as mid-market. And then on the marketing side, we've seen like the results we're seeing from some of the marketing programs, digital programs we're running, to try to drive growth. And we're also investing in building more awareness for Klaviyo in various markets. We're finding in some cases, folks don't know about either Klaviyo writ large or our entire portfolio of products. So as Amanda said, we're very intentional about, like, investing behind things where we see great unit economics, but we do see a number of opportunities to invest. Excellent. Thanks. Congrats again. Our next question comes from Rob Oliver from Baird. Your line is now open. Great. Thanks. Good afternoon, guys. I guess it's kind of a two-part question about SMS traction. AB, you talked about some of the consolidation wins you guys have seen, and, and I know that it sounds as if you're getting pretty solid traction quickly in some of your rollouts internationally with SMS. Just would love, love to hear, I know you don't break out on a quarterly basis, what percentage of your customers are on SMS, but would love to get a flavor for how that's progressing broadly for you relative to your expectations. And then, I guess, Amanda, a side part to that would be, you know, we haven't seen the impact on gross margins that we might have expected with a commensurate ramp in SMS. I know there's other things driving that, but just wanted to reconcile those two things. Thank you very much. Yeah, great. I'll speak to SMS progress, and Amanda can talk about gross margin. Yeah, so while we're not disclosing, like, penetration, we'll continue. We're seeing good adoption, and we'll share some milestones as we hit those. We are seeing good traction, like you mentioned. I think the international expansion, you know, adding Spain, Austria, Switzerland for SMS, as well as adding multimedia messaging in Australia. As we have a, you know, as we think about our international strategy, a big part of it is making sure that SMS is available in those regions as well, and we are seeing good adoption there. You know, a quick example of that is, there's a mattress manufacturer who, you know, was using our, you know, started using us for SMS, adopted or started using us for email, adopted us for SMS, and then because of some of the things, not just the international features, but also some of the SMS-specific functionality we're building. We built a feature around SMS Smart Opt-In that makes it easier to gain consent so that customers, end consumers have to do less clicking to subscribe to an SMS list. That has dramatically increased their ability to grow their SMS program, and that's a feature that we launched in the last few months that's now available to everybody. So we're very excited about the progress we're seeing in SMS. I think there's, you know, still, there's still a long way to go in terms of penetration. Yeah, and, to your question on the Gross Margin front. On Gross Margin, it did come back, come in slightly better than what we had expected, and that was primarily because we continue to see the benefits of the progress that we're making in infrastructure and support efficiencies. And those are offsetting the continued progress that we're seeing and the growth that we're seeing in the SMS business. So one of those infrastructure efficiencies that I would love to highlight is our KMTA, Klaviyo Mail Transfer Agent. We expect to continue to get further leverage in costs over the coming quarters as we transfer more of our mail volume onto our own mail transfer agent. SMS, you know, as Andrew said, continues to grow very well, and so we do expect that as it continues to grow, it's gonna become a bigger portion of our business. That will create some pressure on our gross margins. You know, we're proud of the fact that we've been able to largely offset that to this point and deliver what we see as some pretty best-in-class gross margins, given our product and customer mix. Indeed. Great. Thanks, Amanda. Andrew, thank you. Our next question comes from Tyler Radke from Citi. Your line is now open. Thank you for taking the question. A follow-up question just on the SMB side, and I wanted to ask it more just as we think about behavioral, you know, habits of some of your SMB customers. I'm curious what you observed in the quarter as it relates to, you know, utilization rates of email volumes, message volumes, and contact lists. Did that, you know, did that go up or down in relation to the SMB environment? Secondly, as it relates to, you know, if those SMB customers are seeing weakness in their, you know, consumer purchasing, do you find that translates to higher email and message volumes in order to backfill that demand? If you could just kinda help us understand behaviorally, what you're seeing on the SMB side? Thank you. Sure, Tyler, thanks so much for the question, and overall, I would say that what we saw in terms of behavior in the quarter was pretty consistent with what we've spoken about on our prior earnings calls. You know, we continue hearing from customers about macro pressures. They remain very focused on the value that they're getting from their software. In general, in terms of the macro and the changes in the behavior, we are not seeing it get materially better. We are also not seeing it get materially worse. And we think that we're continuing to perform strong through this environment because, as Andrew mentioned earlier, we are a must-have for these customers. We are a core part of how they drive revenue. We're a revenue engine for them, and being a revenue engine means that when they're thinking about their business, and thinking about the pressures that they're facing, they're thinking about, "How do I efficiently drive that growth?" And Klaviyo is a really important part of that. Maybe I'll add one more comment on top of Amanda. The other thing that we watch is the, you know, percentage of revenue that comes from Klaviyo. And we've seen, talked to a number of customers where that percentage is increasing, and so it kind of doubles down on what Amanda said that we're a revenue engine, and I think folks are looking at, hey, existing customers are great. They've already got existing relationships. It's a great source of demand, you know, when there's, you know, more uncertainty. Thank you. Our next question comes from Nick Altmann from Scotiabank. Your line is now open. Awesome. Thanks, guys. I wanted to ask another question on the international side of the equation, just given the strength there. But so you guys added new countries on the SMS side and spoke to the growth acceleration in the EMEA, and kind of building off of Rob's question earlier, but can you just talk about how much of an unlock some of these international additions have been on the SMS side, and how much pent-up demand you're seeing from some of these geos as you've looked to add SMS in new countries? And then, just as a follow-up, just given the outsized strength on the international side, how do you think about, you know, potentially accelerating those international efforts and investments, just given the strength you're seeing? Thanks. Yeah. I'll, I'll be happy to talk about it. So when we talk about international, we mentioned a couple of things that we're doing, you know, both from a product and a go-to-market side. So we talked about localizing in terms of language. We also talked about localizing some of the marketing and content we're putting in region, and as we build up a larger customer base, more partners, that's becoming a bit of a flywheel. In addition to that, it's making sure all of our products are available. So obviously with SMS, that's very important. And so we're gonna continue to invest on both of those fronts, both languages as well as, you know, SMS and channel availability. That's why we're also investing, you know, thinking about WhatsApp and the role that plays in some markets outside of, you know, outside the Americas. The other thing I'll say, the last thing I'll say, too, is I think, you know, when we think about going to market with partners, we really like to make sure that we're tightly integrated with them and folks that really serve international markets well. So, for example, you know, Shopify talked about their markets products. That's something that we've built out a really tight integration with, so we work really well together. And so we've worked with a lot of other, you know, tech platforms, software platforms that are more prevalent, you know, in Europe and Asia, that's driving a lot of demand and good product market fit. And in terms of investment, you know, we continue to invest in, like, in countries and regions where we're seeing good growth. You know, I think what we're finding with France and what we've the programs we've been able to run there, you know, through digital demand gen, and through our go-to-market teams, I think that's going to become a bit of a template for us in how we approach other markets. And so where we're seeing strength there, we're going to invest behind that. I expect a lot of our customers, you know, they'll increasingly... They, they may adopt us for email first, but then we'll be able to address them, you know, add, add on SMS, CDP, and Reviews. Great. Thank you! ... Our next question comes from Jackson Ader from KeyBanc Capital Markets. Your line is now open. Great, thanks. This is Kyle Diehl for Jackson Ader. Maybe just squaring some of the, the headcount commentary. I think, Amanda, you might have alluded to some, some of the increased margin this period just coming from a little bit lower headcount. Can you kind of help us think about that in terms of sales capacity and, and where you guys currently are, you know, in terms of your plans for the year? And then also on that same note, how, how quickly you can ramp some of the new folks, given, you know, the quickly approaching holiday season here? Thanks. Yeah, I'll take that. And so on the hiring front, you know, I'll say a couple of things. One, we've always been very intentional since we started out of the business about hiring and making sure that headcount was proportionate to the demand and the products that we want to build. So headcount grew slightly from the end of Q1 to the end of Q2. Specifically on the sales side, you know, we think we've got the right amount of capacity, and we're also prepared to scale that as we see more demand. And then to the last comment on the holiday season, one, you know, one of the great things is we do actually see an uptick in, you know, customers that come to us, you know, that want to use Klaviyo over the holiday season. Actually a lot of that growth is coming from our existing customers using more Klaviyo over the holiday season. In that case, you know, we think we're very well staffed across all of our customer teams to meet that demand when folks, say, want to, you know, increase their usage, you know, of one of our core products, email or SMS, we think we're well staffed to cover that demand. Our next question comes from Gabriela Borges from Goldman Sachs. Your line is now open. Hi, this is Callie Valenti on for Gabriela. Thanks for taking my question, and congrats on the quarter. Wanted to ask on, on the mid-market, how much of the momentum that you're seeing do you think is attributable to the broadening of your product set with, you know, CDP reviews and any incremental AI functionality? And then also, to what extent are you seeing customer lands today that probably would not have closed without these new features? Thank you. Yeah, thanks for the question. I think it's a mixture of both. I think it's a testament to the product that we built, the fact that Klaviyo is a data platform, and that we can store all that data and help you put it to work. I think we talked about artificial intelligence and its ability to allow you to do more personalization, to better attribute that and then automatically optimize. One area that we talked about was related to SMS availability and mobile, as we have more of these channels, all in one place, you know, with our CDP and some of its analytic capabilities. I think what we're finding really resonates with larger customers is this idea that all of those features, all those applications, all work together. As we continue to invest in our, you know, that product roadmap and build out those capabilities, I think we're finding that that's, I think, is an even better fit, you know, for larger enterprises. You know, one example who we had in the quarter, I think of some of the questions that you're asking, was an organic food and home goods company who came to us this quarter. They wanted to consolidate their multiple brands onto one single platform so that they could optimize their strategy and have a unified multi-channel reporting. And they chose Klaviyo, in part, because of our portfolio offerings. So that portfolio feature that we recently launched allowed them to easily do high-level reporting across accounts to drive better insights, and they are really excited to get launched with Klaviyo. Great, thank you. Before we proceed, again, if you'd like to ask a question, please press star one. Again, that's star one on your telephone keypad. Our next question comes from Yun Kim from Loop Capital. Your line is now open. All right. Congrats on the strong quarter. Question around go-to-market motion, around new customer acquisitions for mid-market and enterprise customers, which I think you mentioned with a record quarter. So just curious on where is the biggest source of these new 50K plus customers, and, you know, is it still Shopify Plus merchants, or are you specifically going after legacy displacement opportunities outside of the Shopify platform? And also, how much of your incremental sales and marketing investments are focused on going after these large customers outside of the Shopify platform? Thanks. Sure. Happy to answer that. So it's. Again, there's a distribution. We've got a great partnership with Shopify. We have a lot of mutual customers, especially into that mid-market and enterprise. And we have a number of customers that have you know, grown up on other you know, other tech stacks. So we don't break out the distribution, but like, I think it's fairly varied you know at those in those in the higher you know the larger customer sizes. And I think the reason we're winning across all of them is because of our tight integration with their commerce stacks and the ability to store all that data and then put it to work. So, you know, our partnership, our partnership with Shopify is excellent, and then we're looking for ways that we can both help folks that are using other software platforms, as well as those that have maybe homegrown solutions, how do we make sure that we can, you know, help them and their development teams integrate easily? So when we talk about the ease of use of Klaviyo, sometimes that means the ability for these larger enterprises to plug all their systems in. But inevitably, we know that there's gonna be some data sources that they need to use our developer APIs for, and we think we have a really, really strong product offering, a really strong functionality there as well. Okay, great. Thank you so much. We have reached our closing for the question and answer session. Thank you so much again, everyone, for attending Klaviyo's second quarter fiscal 2024 conference call. We hope you have a wonderful day. You may now disconnect.
