Overall Satisfaction with Mailgun
We were sending out transactional emails for our online proofing system which requires back and forth communication between us and the customer. It was being used by our graphic designers to correspond directly to customers during their proofing process prior to printing their artwork.
- Easy Setup
- Works until IP pool gets blacklisted
- Reporting data was detailed
- Customer Service - Customer Support is some of the worst I've ever seen. Over 24 hours to respond to a ticket, no real answers, puts the problem on you, the user.
- IP Pool blacklisting - We were delivering e-mails perfectly fine for 4 or 5 months with bounce rates of about ~2% daily. All of the sudden we were moved to a different IP pool citing our bounce rate was above the 5% threshold. Checking the logs, our bounce rate was fine until we were moved to a different pool, where we were seeing bounce rates of 15%-40% daily.
- Did I mention Customer Service? Asked to be switched to a different IP pool, no response. Asked for a dedicated IP, 36 hours later, a response moving us to a stable IP while we discussed Dedicated IP talks. In the 36 hours it took them to respond I found a different ESP, setup the server, and started sending mail through them.
- Positive: It helped us find a better ESP.
- Negative: Bounced emailed for weeks while trying to find a solution led to unhappy customers and slowed down our printing process.
I used Mailgun first, and after they weren't able to fix my problems or offer any support I switched to Postmark with lower bounce rates, higher delivery rates with more detailed reporting. Setup is more of a to-do but it's well worth it once you start seeing your bounce rate under 1% or .5%.
