Here’s what our customers think of us.

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

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

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

Every time I integrate @postmarkapp with an app I find myself thinking how great the onboarding is. So refreshing.

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

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.

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