Still on the fence about switching to Postmark?

Here’s what our customers think of us.

“When you step back and look at everything Postmark provides, it has everything you’d want if you were building out your own email infrastructure. Instead of it being one part of our stack we have to fight with and maintain, Postmark takes care of everything for us.”

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

Avoid for Production - Zero warning, permanent bans for technical testing.
I spent weeks integrating Resend only to have my account permanently suspended after a single deliverability audit. No warning, no 'sandbox' mode notification, just a total block on a legitimate e-commerce domain. Their 'support' is non-existent when you actually need a human to review a technical edge case. Don't build your business on a foundation that can disappear without a conversation. Extremely disappointing for a supposedly developer-first platform.

I highly recommend @postmarkapp for transactional email. Dedicated to delivery, great help docs, and a clear and simple UI.

Postmark fixed our entire order and shipping conformation email process. Our previous provider had a lot of our emails lost in limbo or not reaching customers for days. Since switching to Postmark, we sleep easy knowing our most important emails are always delivered as soon as a customer orders.

Owner at Noobs

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!
