Migration Guides

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

dunno why but I'm using Resend and the spin up time to actually send an email is diabolical. Sometimes users are waiting 1 min + for a confirmation email. I dunno if it's just free tier things or because I'm based in Canada but I'm not the biggest fan.

We've architected our sending infrastructure to rely heavily on Postmark, and we couldn't be happier. They've been supportive at every step along the way, and have helped us to deliver (and report on) tremendous results for our clients.

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome 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.

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

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...

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.

We now send about 100 Million emails a month with Postmark and we couldn’t be more happy with the experience.
