A superior transactional email service, with unmatched customer support

Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.

Postmark has been incredibly easy to use, is unfailingly fast and reliable, and the Wildbit team is always around for fast, efficient help.

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.

Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.

Postmark has stellar customer service. I don't think I have ever waited more than a few minutes for a response to an email. I also like the degree of interest that the representatives take in my specific circumstances. I felt like they took the time to really understand what I needed and then proposed the best solution for me.

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