Here’s what our customers think of us.
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.
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.
Been using @postmarkapp for all of 10 mins and it's already clear that it's significantly better than AWS SES.
Love the fact @postmarkapp are publicly sharing their status and deliverability details.
Had a horrific experience with SendGrid so i would avoid. We use Postmark and are very happy with it :D
Postmark has made it easier to help our customers because of its accessible and detailed activity log which means we get better information faster.
Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.
Postmark is superior to SendGrid in every regard.
At #Bokio we are now using @postmarkapp instead of @Mail_Gun. I really liked mailgun but we needed far better delivery as our emails are very critical.
