Terrible. I work with it everyday and features are getting worse and worse. They just rolled out making email previews limited. Mmm.. excuse you?! Also, a lot of features don't work- there are ways to choose a background color for each part of an email, but it literally does not work. "Here! Choose an image as background!" Guess what? Doesn't work. I work for a company that refuses to replace Klaviyo because we've been with them for so long, but if you're shopping around, keep looking. Klaviyo will frustrate you so much that you'll consider sending thousands of emails manually lol. NEGATIVE STARS!Edit: THEY REPLIED WITH INSTRUCTIONS TO DO WHAT I JUST SAID I DID *facepalm*. I do know how to add images to the background. IT JUST DOESN'T WORK. Stop wasting my time, you already do that enough!
