Migration Guides

I've tried several of the competitors and finally found Postmark. What a relief to find a straightforward integration for our PHP-based client websites. Setting up was a breeze, the clean and easy to learn UI was enjoyable, and the confidence knowing that web form submission made it to the client? Priceless. Thanks, Postmark, for helping me go from scared and frustrated to confidence in our communication components.

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.

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.

We now send about 100 Million emails a month with Postmark and we couldn’t be more happy with the experience.

Postmark is superior to SendGrid in every regard.

A superior transactional email service, with unmatched customer support

...I've been with Postmark for a few months. Their system is definitely better than SendGrid and SparkPost...two services I tried before moving on to Postmark.

Made the switch to @postmarkapp today. The customer service and delivery rates are awesome, but the thing I love is EVERYTHING IS YELLOW!

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.
