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.

Cliff Chang

Product Engineer at Asana

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.

Dave Marshall

CTO at Childcare.co.uk

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!

Owen Matthews

Creative Director at Ten4 Design

Postmark blows every other transactional email product out of the water.

CEO at Proposify
