Here’s what our customers think of us.
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.
OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.
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.
Postmark blows every other transactional email product out of the water.
Postmark has made it easier to help our customers because of its accessible and detailed activity log which means we get better information faster.
@postmarkapp great job on documentation, and templating. I got up and running in a matter of minutes!
Ok, clearly I hate SendGrid. PostMark 5x better.
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.
Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.
