Still on the fence about switching to Postmark?

Here’s what our customers think of us.

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.

“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”

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

Easy to set up. Great API. Rapid mail delivery and no spam issues. We moved from Mandrill because of terrible deliverability and am pleased to say it’s been well worthwhile....we’ve even saved money. Thanks Postmark Team….you rock!!

General Manager at CircleLoop

...I've been with Postmark for a few months. Their system is definitely better than SendGrid and SparkPost...two services I tried before moving on to Postmark.

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.

As a solo founder, I'm always reviewing and evaluating 3rd party providers. Can I get a better deal? Can I find another service that is more reliable? I’ve stopped asking those questions with Postmark. It hits the trifecta of great customer support, excellent service, and good/affordable pricing. I’m all in for Postmark!

The migration was a piece of cake. The API was very easy to use. Your website is awesome! The only feedback is that I wish there was a "Search" feature in the API Docs, other than that, your website is a perfect work of art!

I finally moved from SendGrid to @postmarkapp for @MetricsWatch. So happy! Great support, awesome product, stellar delivery and speed.
