I've used many different email marketing platforms and MailChimp is the worst by a country mile. I'm having to use it because it's what my client uses, but it is the most terrible experience.It's appropriate having "chimp" in the software's name, because the logic used to build this platform is certainly not human. Full of bizarre restrictions and roadblocks, multiple ways to achive the same thing that are totally incompatible with each other, and totally counter-intuitive methods, it takes literally hours to accomplish simple tasks using MailChimp that other software can do in minutes.Worst of all is the form builder. Or I should say "are" the form builderS. There are several of them. Delete a field on a form and it deletes it in the database. That's not good design. One of the form builders allows hidden fields, the others don't. Worst of all, the forms will only allow new users to complete them. If you want to use one to allow a user to change a field in the database, you're out of luck. MailChimp throws an error if you do that.This software is badly designed, overblown, difficult to use and horrible to look at. It's the worst.
