Migration Guides

We've architected our sending infrastructure to rely heavily on Postmark, and we couldn't be happier. They've been supportive at every step along the way, and have helped us to deliver (and report on) tremendous results for our clients.

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

I came from Mailgun, which gave me headaches. Every second counts when we send an alert to gamers. I love the fact that I can see when mails are opened and how long the whole process took. It just works, which is not so obvious apparently (looking at Mailgun). Thanks Postmark Team <3 !

Postmark has much better deliverability, an amazing dashboard with really good insights.

Btw, I like @postmarkapp way more than @sendgrid.

I had no luck with Sendgrid support when I needed it, compared to Postmark support which was super helpful.

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!

Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.

Sendgrid was giving us countless problems so we switched over to Postmark and went problem-free!
