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.

Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.

I finally moved from SendGrid to @postmarkapp for @MetricsWatch. So happy! Great support, awesome product, stellar delivery and speed.

“When you step back and look at everything Postmark provides, it has everything you’d want if you were building out your own email infrastructure. Instead of it being one part of our stack we have to fight with and maintain, Postmark takes care of everything for us.”

A superior transactional email service, with unmatched customer support

Postmark makes it easy for us to handle all our outbound emails with a high degree of reliability and easy way to get insights into what messages are working with our customers (via tags and analytics).

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. 

We now send about 100 Million emails a month with Postmark and we couldn’t be more happy with the experience.
