I got my account unlocked today after a few back and forth with the support team at Mailgun.
After the first email, they mentioned that they are going to keep the evaluation period ON for the account & that I have to do the steps required under evaluation period. I replied saying that I have done everything so why can’t it be just unlocked. Got a reply stating to send some emails continuously over 4 days to review the stats & then decide whether to unlock or not. Appealed again to this stating that the people signing up are doing double opt-in with mg only & that they have all the stats of people who are on the list.
Finally then today got a revert stating that account has been unlocked.
Thank you guys
