Still on the fence about switching to Postmark?

Here’s what our customers think of us.

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.

We used to get complaints about emails ending up in spam.  After switching to Postmark we’ve had zero issues with that.  Really reduced our headaches.

Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.
