Migration Guides

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!!

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!

Been using @postmarkapp for all of 10 mins and it's already clear that it's significantly better than AWS SES.

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

Made the switch to @postmarkapp today. The customer service and delivery rates are awesome, but the thing I love is EVERYTHING IS YELLOW!

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!

Super customer support, on-boarding process especially incredible. Service 10/10. Struggled with other services like Mailgun — never again. Keep being awesome.

Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.

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.
