Migration Guides

Postmark every day. UX is great. Delivery is top-notch and super fast. I've also used Sparkpost and Mailgun and they just don't compare.

“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”

We used to get complaints about emails ending up in spam.  After switching to Postmark we’ve had zero issues with that.  Really reduced our headaches.

OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

Before Postmark we were using SendGrid, but we had lots of problems with the IP reputation, and they wouldn't move us to another IP range. So we decided change providers, and we are very happy with Postmark. 

Super customer support, on-boarding process especially incredible. Service 10/10. Struggled with other services like Mailgun — never again. Keep being awesome.

Postmark has been incredibly easy to use, is unfailingly fast and reliable, and the Wildbit team is always around for fast, efficient help.

I've tried several of the competitors and finally found Postmark. What a relief to find a straightforward integration for our PHP-based client websites. Setting up was a breeze, the clean and easy to learn UI was enjoyable, and the confidence knowing that web form submission made it to the client? Priceless. Thanks, Postmark, for helping me go from scared and frustrated to confidence in our communication components.
