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

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

Mailgun blocked mail relay access due to an unsafe issue but this was quickly resolved Mailgun blocked mail relay access because there was an unsafe situation. But they responded quickly via email, gave us the correct information to investigate the issue. We were able to explain what happened and the mail relay was re-enabled. I previously working with Sendgrid, had a similar issue and their support was super slow and not supportive at all. I ended up moving to Mailgun and I do not regret the move.

Very good support Very detailed and clear answer from support in order to resolve the issue I got. Great service.

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.
