Still on the fence about switching to Postmark?

Here’s what our customers think of us.

We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!

Sendgrid was giving us countless problems so we switched over to Postmark and went problem-free!

@postmarkapp just started switching over to your service from SendGrid and I'm so happy with everything so far. Great work!

Wow, even after two years of using Postmark I’m still surprised by how much you value your customers!

Made the switch to @postmarkapp today. The customer service and delivery rates are awesome, but the thing I love is EVERYTHING IS YELLOW!

Postmark fixed our entire order and shipping conformation email process. Our previous provider had a lot of our emails lost in limbo or not reaching customers for days. Since switching to Postmark, we sleep easy knowing our most important emails are always delivered as soon as a customer orders.

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

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.
