Migration Guides

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.

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

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

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.

Love the fact @postmarkapp are publicly sharing their status and deliverability details.

@postmarkapp great job on documentation, and templating. I got up and running in a matter of minutes!

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

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.
