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.

MailGun makes deliverability easy MailGun has made it easy for us to manage outbound mail for an assortment of our clients needs. Their support is great when there is an issue they work with us to resolve it and move forward. With the current cyber security and spam landscape its important to have a deliverability partner that we can trust to keep our applications running.

The support is really good! The support is really good, either by chat or email. Shared IP's, in my experience are often blacklisted, so that's why I give 4 stars. We switched to a static IP because of this.

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

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
