Migration Guides

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.

Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.

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.

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

Btw, I like @postmarkapp way more than @sendgrid.

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

Postmark has much better deliverability, an amazing dashboard with really good insights.

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

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.
