Cheers to Hispanic Heritage Month 🍸 Last Friday, we hosted a virtual mixology class with the team where we made margaritas, caipirinhas, and palomas!

"Who wrote this?!" - Dave Gerhardt We set out to build the worst email ever and shared it with Dave to gauge his reaction. To achieve this, we played Mad Libs with marketers we met at Drive by Exit Five. How did we do? Have you seen a worse email?

Happy Hispanic Heritage Month! Our Sazón & Soul community invited the team to take part in a piñata making class on Friday to help celebrate. Plus, we ate some tasty Mexican candies like Pulparindo and Vero Elotes. What's your team doing to celebrate Hispanic Heritage Month?

The tech industry pulled back on junior engineers. We gave them an office. This fall, five University of Waterloo co-op students are joining our Engineering org for a 16-week term. They'll work out of a physical office in downtown Toronto. Why are we doing this? Because they're the future. "We want to invest in the next generation of software engineers," says Engineering Manager Marcel Van Der Linde. "A lot of companies have pulled back on early-career hiring. We think that's shortsighted." "It's also a bet that pays off both ways. The next generation of engineering students have been AI-native since their first year of school. They almost certainly think about and approach their work differently than many of us who have been in the industry for decades already. We're hoping to learn from them, too." Instead of having the co-op students do sideline work, they'll be embedded directly onto one of our squads: In-App, Messaging Channels, Workflows, Content, and Audiences. They'll focus on tangible, valuable, customer-facing roadmap work alongside the rest of their team. We're also flying engineers and leaders into the Toronto office throughout the term. Over the 16 weeks, the co-ops will work alongside dozens of people from across the company and gain direct access to leadership and customers. To top it all off, each student will wrap up their term with a presentation directly to the CEO. We'll be sharing their stories here over the next few months so keep an eye out!

Our internal AI customer support agent was experiencing an issue. Instead of delegating the fix, our VP of Engineering, Paul Senechko, closed the debugging gap personally. Here's why he thinks this is the new leadership move in an agent-first world: bit.ly/4qM4ZWe

The @GeorgiaAquarium needed to made a splash with their marketing campaigns 🌊 So Brian Lee, Digital Marketing Manager, switched to Customer.io. The result was a monthly send volume increase by more than 2,000%. More importantly, they were able to unlock personalization at a scale the team had never been able to achieve before. He and Data Scientist Becky West recently spoke with us about their experience using Customer.io. And we got to visit them at the Georgia Aquarium to film the conversation. Not every testimonial video includes stunning scenery like this. Just look at all those fish! 😍
