Still on the fence about switching to Postmark?

Here’s what our customers think of us.

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

Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun

Postmark has made it easier to help our customers because of its accessible and detailed activity log which means we get better information faster.

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

Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.

Super customer support, on-boarding process especially incredible. Service 10/10. Struggled with other services like Mailgun — never again. Keep being awesome.
