Still on the fence about switching to Postmark?

Here’s what our customers think of us.

Postmark without question. High-quality product and unreal support. Dabbled with all over the years, and SendGrid/Mailgun were some of the worst experiences I’ve ever had in terms of both product and support.

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.

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.

Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.

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