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.

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).

Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.

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.

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!

At #Bokio we are now using @postmarkapp instead of @Mail_Gun. I really liked mailgun but we needed far better delivery as our emails are very critical.

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

...I've been with Postmark for a few months. Their system is definitely better than SendGrid and SparkPost...two services I tried before moving on to Postmark.
