At Postmark, transactional email isn't just an add-on. It's at the heart of what we do. Let’s put an end to deliverability issues—give Postmark a spin, and get 100 emails/month (every month!) at no cost.
Let’s talk about the elephant in the room: You were just looking for Mailchimp Transactional (the artist formerly known as Mandrill) alternatives, and now you’re here. On the Postmark website. And Postmark, you guessed it, is a Mailchimp Transactional alternative. But we aren't here to start a smear campaign. Actually, there are a lot of great reasons why folks love Mailchimp Transactional:
And we’ve heard from folks like you that there are some not-so-great things about Mailchimp Transactional:
Get 100 emails/month for free, and take a look at our migration docs for Mailchimp Transactional.
Our rates? Transparent as a glass of water. No marketing plan required.
Your customers expect transactional emails to arrive in the inbox immediately—not eventually. We don't just claim speedy delivery. We share live time-to-inbox data so you can judge for yourself.
Our goal at Postmark is to make email delivery dead simple. We have an acute focus on our email delivery rates—that means getting your email into the inbox, not the spam folder. Otherwise, using Postmark isn’t justified, no matter what additional features we offer.
Postmark is loved by developers all over the world because it just works.
There’s no VIP section for support with Postmark. You can email us and usually hear back in a couple of hours, or you can reach us via live chat during business hours—and we won't redirect you in an endless loop. We have a 95% customer satisfaction rating for a reason.

We use Postmark for the important emails: password resets, order confirmations, email confirmations. These are the emails our users, and their customers, can’t afford to miss.
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!
Postmark’s API is consistent, super stable, and fast. The UI has remained consistent. The brand looks almost the same. There's a sense of continuity rather than flux. Not constant changes in the branding or UI, or chasing unnecessary features. Postmark has done a really good job of growing and changing in little ways that are beneficial, not detrimental, to me as a customer.
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!!
