Migration Guides

Switching to Postmark? Our handy migration guides have everything you need to know about making the shift.

Still on the fence about switching to Postmark?

Here’s what our customers think of us.

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

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.

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!

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 blows every other transactional email product out of the water.

I don't plug products much, but good god damn @postmarkapp has made us very, very happy. An order of magnitude better than running our own mail.

Postmark fixed our entire order and shipping conformation email process. Our previous provider had a lot of our emails lost in limbo or not reaching customers for days. Since switching to Postmark, we sleep easy knowing our most important emails are always delivered as soon as a customer orders.
