@postmarkapp just started switching over to your service from SendGrid and I'm so happy with everything so far. Great work!

“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”

Password reset emails delivered by @postmarkapp arrive in gmail in 1 second (vs 64 seconds for SendGrid)

Postmark has made it easier to help our customers because of its accessible and detailed activity log which means we get better information faster.

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.

Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun

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.

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.

Been using @postmarkapp for all of 10 mins and it's already clear that it's significantly better than AWS SES.
