Migration Guides

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.

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.

We've architected our sending infrastructure to rely heavily on Postmark, and we couldn't be happier. They've been supportive at every step along the way, and have helped us to deliver (and report on) tremendous results for our clients.

Postmark blows every other transactional email product out of the water.

Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.

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.

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.

@postmarkapp great job on documentation, and templating. I got up and running in a matter of minutes!
