Migration Guides

Wow, @gmail deliveries via @postmarkapp is really fast, ~1s! Seems to have an excellent #ISP reputation. #transactional #mails #service

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.

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 needed a solution specifically for transactional emails and improved deliverability. After researching all of the options for our user emails, we landed with Postmark as the clear choice for transactional emailing.

A superior transactional email service, with unmatched customer support

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.

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

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!

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.
