Migration Guides

Easy to set up. Great API. Rapid mail delivery and no spam issues. We moved from Mandrill because of terrible deliverability and am pleased to say it’s been well worthwhile....we’ve even saved money. Thanks Postmark Team….you rock!!

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.

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.

Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.

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

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

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

The migration was a piece of cake. The API was very easy to use. Your website is awesome! The only feedback is that I wish there was a "Search" feature in the API Docs, other than that, your website is a perfect work of art!
