I had to switch from it last minute, because one of my forms wouldn't activate, actually, I did get the Form Activated to appear, and some emails passed, but then It was still deactivated, and found myself in an endless loop. Idk, but I had to go with a paid option so my boss would be reassured it would work on monday.
Anyway a few more I found when I had to switch last time, I went with usebasin.
