Thanks, Jennifer and good morning everyone. It has been an exciting first half of 2021 at Groupon and I'm pleased to report another solid quarter of financial results. In the second quarter, we generated nearly $430 million in global, Local billings, the highest quarterly level since the pandemic began and $41 million of adjusted EBITDA. The macro recovery as expected is proving to be an organic tailwind as economies around the world reopen and consumers get back to enjoying Local experiences. While the recovery in North America continue to ebb and flow, second quarter North America Local billings grew 20% versus the first quarter and 67% of 2019 levels, the highest quarterly recovery rates since onset of the pandemic. We ended the second quarter with $15.2 million active North American customers which was stable compared to the first quarter and is an important milestone that you'll hear more about from Melissa later in the call. For our international business, in the second quarter countries began relaxing COVID restrictions as vaccinations accelerated and in June International Local billings reached the highest recovery rate since the onset of Wave 2 in October 2020. International Local billings also stepped up nicely quarter over quarter growing nearly 30% in the second quarter versus the first quarter, but similar to what we've seen in North America, we expect performance to ebb and flow across international markets. And as we've said before, we expect a longer recovery cycle in International restrictions have been more prolonged and stricter and the vaccination roll-out has been slower. As we leverage these macro recovery trends to our advantage we are also continuing to execute on our growth strategy. We told you that our goal was to grow high quality local inventory. So far our efforts have centered around growing Offers inventory within Beauty and Wellness and removing restrictions on deals across the marketplace. We've also begun to modernize our marketplace with a new customer experience and new feature sets for our merchants, including expanded self-service. Overall, despite the overhang of the pandemic, we are seeing green shoots that give us confidence in our ability to reshape Groupon into a destination for local experiences, which we believe will provide a foundation for growth in the years to come. Our growth thesis is rooted in our ability to deliver the value proposition and our customers and merchants wants. Everything we're doing is focused on improving these value propositions. We want to improve the ease with which merchants can interact with the Groupon marketplace, extend their reach to new and existing customers and give them the monetization levels they need to achieve healthy unit economics. Likewise for customers, we intend to expand our wallet share by giving them the value, selection, and convenience they want. Expanding our inventory is a key element of our growth strategy and our teams have been making meaningful progress on two fronts. Bringing back pre-COVID supply to our marketplace and going offers and repeatable inventory. First, let me touch on the team's progress on bringing merchants, particularly top merchants from 2019 back to the marketplace. Many of you have been asking us about the health of our merchant base, so I wanted to provide you with some additional color to highlight our progress today. My comments will focus in North America which is leading the way. When we think about recovery on merchant base, we believe the fastest way for us to re-energize our local category is to reactivate our top supply. So we have placed a lot of focus on this call and our efforts are beginning to pay off. At this point, we have brought many of our top merchants back to the marketplace. While we are encouraged by our progress and being these merchants back retaining them we know we have to move this number even higher. As I said, we're confident we can continue to do that and here's why. First, our team is in active dialog with our top merchants who are not yet back on the platform and many of them are telling us they want to come back to Groupon, but the timing is not yet right. This is particularly true among our teams to be merchants, which on a billings basis with our largest vertical in 2019. We are hearing from many of these merchants that there are capacity constraints, largely driven by labor shortages, lingering COVID restrictions, and high consumer demand. This has led to a supply-demand mismatch. However, other verticals like Beauty and Wellness and Home and Auto are more recovered and we have more of these merchants back in the Groupon marketplace. We believe this demonstrates that they view Groupon as a valued partner. And second, as we continue to engage with our top merchants we are seeing top supply metrics improved weekly across all vertical. We believe merchant capacity constraints are transient and that we will successfully bring back top supply, although the timeline to achieve this will likely extend into next year. The great news on this front is that as our top merchants return, they will be returning to a fundamentally improved Groupon experience one that does a better job of driving customers through their doors. You're hearing that we still have some work to do on this front, but our progress bringing top supply back on the platform is certainly trending in the right direction. To help you triangulate and why it is important top supply recovery has been correlated with our bookings recovery in North America Local. We believe that has high quality merchants return to our marketplace it's a stimulating customer demand. Beyond just our top merchants we have broad supply with market leading selection of local experiences that support the vibrancy of our marketplace. We are leveraging our sales team, self-service, and our inventory partnerships to continue to grow our inventory base and further strengthen our competitive position. While we are focused first and foremost on recovering our top supply, we are also doing all we can to help small businesses finds it's footing as they reopen their doors. We love seeing these local businesses come back and partnering with us, which helps to strengthen our position as the destination for Local. So, we talked a bit about recovery let me now switch gears and update you on our growth efforts. The team is making steady progress on our inventory initiatives, which we believe will allow us to transform our marketplace by growing high-quality local supply. As we've discussed in previous calls, in North America in 2021 we're focused on removing repeat restrictions and deals across all verticals and increasing the average number of listings per Beauty and Wellness merchant. I'm excited to announce that as of today's call more than 70% of our deal Inventory is now repeatable. This is an important milestone as we strive towards our long-term goal of increasing purchase frequency and overall marketplace velocity. Unrestricted deals will give consumers the opportunity to engage more frequently with more inventory to repeat purchases. While it is very early days, which means we haven't fully leaned into marketing these deals, we are encouraged that merchants who have lifted repeat restrictions saw initial 2% lift in units per customer. We have also hit our goal to increase the average number of listings per Beauty and Wellness merchants. In the first half of 2021 we grew inventory within our North American Beauty and Wellness vertical with a majority of this growth driven by Offers. In fact listings per Beauty and Wellness merchant has grown over 20% since we launched Offers, which means in on average these merchants now have about four options for purchase in the Groupon market place. Digging in one level deeper, Beauty and Wellness merchants leverage Offers have nearly four times more liftings and merchants only list deals. This further demonstrates that our merchant value proposition is resonating and our new office product is unlocking Groupon's opportunity with Beauty and Wellness merchants. We will continue to focus on driving listings per merchant higher when and where it makes sense. Let me provide some additional context for how this progress is showing up in merchant and consumer behavior as well as our business As we look at the four cities where we tested Offers, Detroit, Denver, Dallas and Seattle during the second half of 2020, we can see the impact of Offers. Offers has now been part of our sales pitch in these markets for about a year. We're still early but we'd be seen a positive response from both sides of our marketplace. So here's where we are today. On supply side merchants are embracing Offers. The initiatives we have in place are driving Beauty and Wellness supply growth in our marketplace and we are testing these initiatives and others to power supply growth in other verticals. On the demand side, customers are also responding particular high-intent customers. That said, again we're still a bit early and while we're seeing encouraging signals we have work to do to unlock our full potential. It's also really important to keep in mind that our markets have yet to fully benefit from our new customer experience for marketing investment. The pandemic has created a lot of noise and there's a lot of seasonality that makes measuring incrementality difficult. Remember however that we've tackled the two root causes that have prevented customers from doing more with us. With unrestricted supply which now allows customers to buy more than 70% of our inventory again and again and we systematically gone after full menu with merchants so they can do more with us and help give customers the broader selection of experiences they want. These are fundamental challenges that we had to overcome. Bottom line, we have high conviction that unrestricted inventory and providing new inventory products will help us drive demand over time. As we continue to scale elements of our growth strategy we're positioned to leverage these elements throughout our business to create even more opportunities to drive growth, such as launching new products, focused on driving frequency, rolling out new branding, and exploring new ways to attract loyal customers. Now that we are beginning to make substantial progress, both recovering our pre-COVID supply and unlocking merchants potential to do more with Groupon, we're ready to leverage proven marketplace tactics like inventory multi-packs and other merchandising initiatives that were not possible before. Let me take you through how we are leveraging these marketplace tactics within our strategic priority to modernize the marketplace experience from merchants and customers alike. Let's start with the merchant experience. We're leveraging technology across our merchant platform to deliver the ease, reach, and monetization that local businesses want from Groupon. We have launched new features to significantly improve our self-service capabilities and it is now much easier for our merchants to create, update, and optimize listings. In short, Groupon is becoming a better partner to our Local merchants around the globe. A best-in-class self-service option solves two key challenges for us. Number one, it addresses a key merchant paying point and number two, it creates leverage for our sales team as we expand our local inventory. New and existing merchants alike are transitioning seamlessly to our self-service platform. Let me provide a little color on how self service is beginning to show up in our merchant data. In the past 12 months, we've made strong progress getting just to adapt self-service. In the second quarter alone, nearly 50% of the deals launched in North America for last via self-service. We expect this number to continue to grow over time. Moving forward, we believe self-service will be an important and standard way for merchants to interact with Groupon. Now that we have made significant progress optimizing our merchant platform to handle standard business operations, we are moving to enhance our feature set with capabilities that are need to Groupon and our opportunities. For example, in the fourth quarter of 2020, we launched a new recommendations feature, which is beginning to deliver results. Among our top merchants those that have leveraged our recommendations realized nearly 20% more bookings versus merchants who did not. In late June, we launched a significant new recommendations feature set, the Merchant Advisor, a tool that further strengthens our ability to give our merchants more strategic campaign recommendations to drive growth. This new feature dynamically analyzes merchant campaign performance and provides bespoke recommendations that help merchants manage their entire portfolio of listings, such as recommending new deals to launch based on a merchants menu of services. We plan to scale this to all merchants in the third quarter and believe it will provide merchants with even more actionable insights to drive growth. A win-win for both merchants and Groupon. In addition to self-service we are also leveraging partnerships integrations when we see an opportunity to accelerate improvements to Groupon merchant experience. A great example of this is our new partnership with Booksy, a popular Beauty and Wellness appointment app. Now existing Booksy merchants can easily connect their inventory to the Groupon marketplace and Groupon will be able to offer our merchants free access to Booksy suite of scheduling and business management tools. Bookable inventory is an important characteristic of high quality supply, particularly in the Beauty and Wellness vertical and these types of partnerships can help accelerate growth of our bookable inventory, while also enhancing the customer experience. Offering a portfolio of free and paid merchant services as part of our overarching long-term strategy to provide merchants with a full-service platform that they can leverage to build and grow their businesses. This is a great segue into our progress modernizing customer experience. By now, many of you in North America have interacted with our new customer experience. As a reminder, our overarching goals into experiences to drive sell-through of our expanding inventory base, grow purchase frequency over time, and begin to bend the customer perception of Groupon from a inspiration only marketplace to a destination for local experiences. We want to deliver a modern, engaging, personalized discovery experience that will give consumers highly relevant search results and recommendations to consider and interact with that will help drive conversion over the long run. And drive more customer engagement with our content which should also lead to an increase in purchase frequency. With no means of consumers coming to Groupon everyday interacting with our homepage we have a unique opportunity to educate consumers and how they can leverage our platform to explore the world around them and participate in the 80+ Grouponable moments happening every year. We've made a lot of progress on this mission critical initiatives and as of last week our new customer experience had been launched to 100% of North American users across the app mobile web and desktop. A huge shot out to our product and engineering teams for all their hard work to get this new CX launched. We had in for plan and change our customer experience in over 5 years and this launch is an important point in our journey to becoming the destination for local. In addition, it was also completed in a much shorter time frame than any previous changes going from concept to delivery in just six months. Let me share a few early learnings, 90 days post launch. We are prepared to see a typical drop in conversion rate that usually happens when we launch a new CX. While conversion rates are still below pre-launch levels we've been encouraged to see the impact to conversion was less than anticipated and seen conversion improve steadily since March. Engagement is also a bright spot for us. We're seeing customer spend more time engaging with our marketplace. Our homepage bounce rate has gone down and category page views have gone up as customers spend more time browsing exploring local experience. Finally, the early read on our likelihood to purchase survey indicates that our new CX helping to shift our brand perception. While based on a small sample size through this data we have seen that our new experience is outperforming our old experiences as customers tell us that Groupon is showing them the businesses and listings they're interested in and helping them discover new experiences. In terms of what's next for our new CX, this recent launch is only the beginning. Now that we've unlocked new inventory growth avenues and have launched a foundational new user experience that is local first and showcases Groupon as a destination marketplace, we're focused on improving the way we surface full menu inventory options in building and launching more features to drive more engagement and repeat purchases. One example of our inventory, merchant and customer initiatives are coming together to pave the path forward for the New Groupon with our recent planning of inventory market apps, which allows customers to buy multiple experiences in a single purchase from a merchant at a discounted price. We're exploring how we can leverage multi-packs and eventually bundles to drive unit growth. While this product is still in early development the initial read from customers has been positive, leading us to believe that we can capture additional wallet share. Less than a year ago a product like this would have not been possible. We've been able to create an entirely new product that speaks directly to our merchant and customer value proposition. And as I mentioned, we believe this is only the beginning. With our progress on the inventory front and the rollout of our new CX in North America and as local communities continue to reopen around the world, we've begun to lean into marketing to maximize the impact of our progress. As we look to re-educate customers and expand the perception of our brand from an episodic inspirational marketplace to a destination marketplace. We are being strategic with our marketing investments and we are focusing on deploying resources in a balanced way to make all parts of the funnel work harder. Being strategic also means that we'll continue to assess the impact from the Delta variant and pandemic related constraint. In the second quarter, we continued moving our spend up the marketing funnel with the ultimate aim of reshaping our brand perception as a destination for local. We saw some great results with our mid-funnel efforts and tested new channels to reach a new younger audience. We've also begun to showcase and leverage our brand repositioning through creative marketing. This week we launched a new brand campaign Grab Life by the Groupon, asking people to choose is going to do accept life as it is or grab life like their life depends on it. This campaign brings our inventory and marketplace modernization work to life and we're excited about this campaign's potential among customers who are ready to get out and explore our local communities. Before I turn the call over to Melissa, I want to take a step back remind everyone of everything we're doing to transform the Groupon marketplace. If you look back over the past 10 years Groupon was really only able to offer one local inventory product deals. Merchants had only one way to interact with Groupon and there was no opportunity for them to do more with us. And it's only one product and limited purchasable inventory we trained customers to think about us only episodic. We fundamentally altered the customer merchant value propositions over the course of just the last year. We're bringing our merchants to ease, reach and monetization they need to help their businesses succeed with Groupon and giving our customers the value, selection, convenience that they want. As we've shared today we've already made significant progress rolling out our new value propositions. It will take time to influences the hearts of minds of our customers given our long-standing reputation as an inspiration marketplace, but we're well on our way and we're excited about what lies ahead. With that, I'll turn the call over to Melissa to provide insights on our financial performance.
