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

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

I am baffled that anyone would choose Sendgrid over Postmark. If they tried both, they probably wouldn’t. Delivery rates are just night and day honestly!

Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.

You have an excellent user interface and very good spam reputation service. Combined with the pay-what-you-use subscription a better alternative to Mailchimp and its expensive Mandrill moneymaking machine.

I don't plug products much, but good god damn @postmarkapp has made us very, very happy. An order of magnitude better than running our own mail.

Postmark has stellar customer service. I don't think I have ever waited more than a few minutes for a response to an email. I also like the degree of interest that the representatives take in my specific circumstances. I felt like they took the time to really understand what I needed and then proposed the best solution for me.

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!
