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.

Had a horrific experience with SendGrid so i would avoid. We use Postmark and are very happy with it :D

I finally moved from SendGrid to @postmarkapp for @MetricsWatch. So happy! Great support, awesome product, stellar delivery and speed.

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

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

As a solo founder, I'm always reviewing and evaluating 3rd party providers. Can I get a better deal? Can I find another service that is more reliable? I’ve stopped asking those questions with Postmark. It hits the trifecta of great customer support, excellent service, and good/affordable pricing. I’m all in for Postmark!

...I love the new templates feature in postmark, BTW! that’s already saving me some time. Look nice too.

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

I've tried them all ; i'm still am to some extent because i was too lazy to migrate everything. This being said, postmark is my absolutely top choice for features AND deliverability. Resend is only good at UI (and that's a shame, because i really liked their UI) but damn, it is so slow and has so many bugs that i could not use it anymore...
