Setup with MailGun was Quick and Easy Setup with MailGun was quick and easy. I contacted support to work through a couple of issues. Support quickly resolved those issues and had our new SMTP sender functioning in short order.

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.

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)

Nice and helpful support team Nice and helpful support team. Flex plan is also seems good for developers have projects on their baby steps. It would also be much nicer if emails did not usually go to junk, maybe this will change over time.

They know what they are doing We had some issues with one of our e-mail-domains. Even with the Flex Plan Mailgun had quick repsonse times and in depth analysis of the problem. They helped me out solving the issue. The world of e-mail can be a maze when you are experiencing troubles. Mailgun can help you find your way.
