Zagomail used to be excellent. Initially, it was great, so I invested over $400 in a lifetime deal they offered (sent to my email), upgrading to include subaccounts. Now, after onboarding clients, the system doesn't work. I've sent countless emails and just want it fixed. I'm feeling so disappointed and duped. I will update my review as I get a response. It's also a shame that AppSumo would not put pressure on a brand to follow through and check in.
