Overall Satisfaction with Mailgun, from Pathwire

We use Mailgun for all our outbound emails from our Rails app. This includes transactional emails to our users but also is the backbone behind our reminder system. Our reminder system sends periodic emails on behalf of our users to their customers. We also use their API to track the delivery status of each message and expose that information to our users.

Pros

  • Their API and webhooks are excellent and reliable
  • They have great tools that help us increase our deliverability and reduce the chance of getting marked as spam
  • Their suppression lists are easy to manage

Cons

  • Their management user interface is a bit slow, searches take quite a while which can be frustrating. But we don't use this interface often, we mainly use Mailgun through their API behind the scenes, and it works great.
  • Reliably deliver email through their API
  • Managing suppression lists
  • Custom, clean, IP addresses to ensure deliverability
  • Their support has been responsive and helpful
  • We rely heavily on them for sending out reminders, which is a core part of our business. We send thousands of emails per day, and have never had a disruption that has caused us embarrassment with our customers.
We chose Mailgun over sendgrid and Postmark because we really like their API. We have stuck with them because they have never given us any reason to switch. Their reliability is superb and their API remains excellent. sendgrid and Postmark are both good in their own rites, but we have not regretted our decision to use Mailgun and have never considered switching.

We have found Mailgun to be suited very well for the email sending needs of a Rails app. It is excellent for transactional emails and easy to integrate into a Rails app. We have also found it to be great at delivering mass mailings on behalf of our customers. I've not found a use case where it isn't a good fit with regard to email sending. We are very pleased with their service.

Mailgun, from Pathwire Reliability

Over the past six years, Mailgun has scaled with our growth very easily. We haven't had to make any code changes to handle our larger volume today, and their pricing has scaled naturally with our growth. As far as I know, there is nothing we will need to do in order to grow 10-fold. Mailgun just handles the load really well.
There have been a few minor outages through the years, but nothing more than a few minutes. These small outages are to be expected in any kind of a SaaS product, but Mailgun handles them very well. We designed our software to just retry sending after a while if there is an outage. As far as I know, we have never had to do more than a few retry cycles. This is all automated on our end, so we rarely even notice. Our customers have never noticed any mail sending outages.
The API and the deliverability of emails is excellent. Their API is very responsive and performs perfectly fine. I have no complaints there. Their management interface though (accessed through the web) is pretty slow though. Searching through lists of emails when I'm tracking down a problem for a customer can take 10+ seconds which is annoyingly high for a modern web app.
