Helpful support When our login keys got compromised, Mailgun immediately blocked our account to prevent any damage. The support we got from Mailgun to solve the problem was very helpful and fast. Great job! Hans Meijs

They have locked down our sending ability They have locked down one of our domains, claiming leaked smtp credentials (we do not use smtp, so could not have leaked any creds - they provided no further details, nor any logs, nothing, and we have no unauthenticated mail sent via our domain either). There's no local Aussie phone number to call, support does not seem to respond on Australian business hours - so god knows when can we get it unlocked. Go somewhere else if you want reliability. This is an abysmal and un-acceptable way to deal with a paying customer of long years.

Great customer service, could be docs tho Not used the mail sending part much yet, tho I'm sure it's fine :) Service very good. Quick and clear customer response. Docs could have explained it a bit better and then I'd not have needed to ask them! (Flex plan can be selected if you don't send a lot of email - just get the trial, then unsubscribe from it before it runs out, and switch to flex plan)

While we are not the biggest account… While we are not the biggest account with Mailgun, the support team has always gotten back to me in a timely fashion. The last support call Mailgun helped our team in a big way by evaluating our current configuration and enabled a setting for us that made all the difference to enhance our workflow and made our business look polished. Thanks
