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.

We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!

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

Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.

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!

Love the fact @postmarkapp are publicly sharing their status and deliverability details.

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

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 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.
