"We started working with Matt and Sweysive two years ago, and it’s been an amazing partnership. I’m so happy to be working with them. Working with Sweysive is always a pleasure. It doesn’t matter what time of day I’m communicating—it seems like he’s always up and responding to messages, which is just crazy. Whether it’s Slack, email, or weekly catch-ups, the whole team is just super responsive to any issues we have. Whether it’s email marketing or just general e-commerce, it’s great. I’m always hesitant to recommend any agencies to people I work with because you never know if they’re going to get the same level of service that I get. But when it comes to Matt and Sweysive, I do not have any reservations at all. The guy just works his tail off every day, loves what he does, and that comes through in the designs and emails that he sends to us. It’s amazing to have him, and we’re lucky to have him as part of the team."
