A superior transactional email service, with unmatched customer support

Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.

Had a horrific experience with SendGrid so i would avoid. We use Postmark and are very happy with it :D

We now send about 100 Million emails a month with Postmark and we couldn’t be more happy with the experience.

👉 @postmarkapp is one of those services that you really enjoy using even if it's a very simple service. Everything feels "right" 👏

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.

We used to get complaints about emails ending up in spam.  After switching to Postmark we’ve had zero issues with that.  Really reduced our headaches.

...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.
