Looking for a Mailchimp Transactional alternative?

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.

👍 Why folks love Mailchimp Transactional:

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:

  • 💼 Sub account support
  • 🐒 Backed by Mailchimp, the email elders
  • 📧 Handy templates for transactional needs

👎 But hey, no one’s perfect!

And we’ve heard from folks like you that there are some not-so-great things about Mailchimp Transactional:

  • 💸 Confusing pricing (what is a “block” of emails anyway?) and the occasional upselling mischief
  • 🥈 Transactional email is an add-on—not a core product
  • 📬 Emails don’t make it to the inbox as reliably as other providers
  • ⏳ Customer support could be...quicker?

Sound familiar? Reduce the headaches and give Postmark a try!

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!!
