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).
Password reset emails delivered by @postmarkapp arrive in gmail in 1 second (vs 64 seconds for SendGrid)
Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.
I highly recommend @postmarkapp for transactional email. Dedicated to delivery, great help docs, and a clear and simple UI.
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.
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.
Sendgrid was giving us countless problems so we switched over to Postmark and went problem-free!
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!
“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”
