Here’s what our customers think of us

Postmark has a reputation for high quality. Even though there are several good companies, we were convinced by Postmark’s clear documentation and transparent roadmap. Further, building email infrastructure is really a partnership — we wanted to invest in a platform that would continue to grow along with our needs, not one that was fairly static and falling behind the technology curve.

I was shocked to see Postmark open rates were an 11% improvement over SES in our test. Needless to say we started sending all of our transactional email through Postmark.

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!
