Migration Guides

Postmark without question. High-quality product and unreal support. Dabbled with all over the years, and SendGrid/Mailgun were some of the worst experiences I’ve ever had in terms of both product and support.

@postmarkapp just started switching over to your service from SendGrid and I'm so happy with everything so far. Great work!

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

Wow, even after two years of using Postmark I’m still surprised by how much you value your customers!

Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun

I don't plug products much, but good god damn @postmarkapp has made us very, very happy. An order of magnitude better than running our own mail.

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!!

You have an excellent user interface and very good spam reputation service. Combined with the pay-what-you-use subscription a better alternative to Mailchimp and its expensive Mandrill moneymaking machine.

The migration was a piece of cake. The API was very easy to use. Your website is awesome! The only feedback is that I wish there was a "Search" feature in the API Docs, other than that, your website is a perfect work of art!
