Migration Guides

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...

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

Super customer support, on-boarding process especially incredible. Service 10/10. Struggled with other services like Mailgun — never again. Keep being awesome.

Easy to set up. Great API. Rapid mail delivery and no spam issues. We moved from Mandrill because of terrible deliverability and am pleased to say it’s been well worthwhile....we’ve even saved money. Thanks Postmark Team….you rock!!

Wow, even after two years of using Postmark I’m still surprised by how much you value your customers!

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

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.

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

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