Migration Guides

I came from Mailgun, which gave me headaches. Every second counts when we send an alert to gamers. I love the fact that I can see when mails are opened and how long the whole process took. It just works, which is not so obvious apparently (looking at Mailgun). Thanks Postmark Team <3 !

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

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.

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

We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!

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

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

Postmark every day. UX is great. Delivery is top-notch and super fast. I've also used Sparkpost and Mailgun and they just don't compare.

I am baffled that anyone would choose Sendgrid over Postmark. If they tried both, they probably wouldn’t. Delivery rates are just night and day honestly!
