Best when you're using G Suite and have to migrate quite a few email addresses. The UI is great and easy-to-use. When you do hit a snag, their customer service is terrific at locating and fixing the problem. I'd definitely recommend.

Installed and got this message "The number of available free migrations for this domain has been reached. Please sign up to Carbo and get unlimited migrations for your domain.", how can it be possible? We didn't do anything before with this app. Uninstalled.

I got one migration with the install of this app. I didn't realize I only got one migration so I then ran a test to see if it will do what I want it to do and it worked fine but then I went to do another (real) migration and I realized I can't because I used up my one "test" AND because I'm a nonprofit, I can't get the app. This is extremely disappointing. I wish you all could offer another alternative that was a paid version or something that nonprofits could take advantage of.

Nothing imported and no followup from support. Total waste of $10 bucks.
