I recently had to setup a few mailchimp campaigns for a client and so found myself using the new UI quite a lot. Their new design has quite a lot of UI bugs and things that make no sense. Its all fixable with feedback, but it would've been nice if they'd beta tested this design first. It feels rushed.
Yep, although it's still 10 times better than their old interface.
It's been a couple of months now I think (?) since the redesign and if they had been proactive about it, most of these should have been fixed already. It makes me believe that they're not using usability testing, which makes no sense for a company their size. Or maybe they do, and that really is the unintuitive outcome their tests have shown to be the least confusing to users. Would be hard to believe, though...
Usability testing is hard to get right. If you have 2 bad ideas, all it will show you is which is the least bad. They probably A/B tested this two-step layout with a text-only prompt and it did better.
