OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.

I highly recommend @postmarkapp for transactional email. Dedicated to delivery, great help docs, and a clear and simple UI.

BTW @postmarkapp is bloody lovely

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.

My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.

...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.

We use @postmarkapp. Incredibly reliable service run by incredible people.

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.

Postmark is superior to SendGrid in every regard.
