Here’s what our customers have shared

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.

Postmark is superior to SendGrid in every regard.

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.
