Migration Guides

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.

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.

@postmarkapp great job on documentation, and templating. I got up and running in a matter of minutes!

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.

I SERIOUSLY LOVE YOU! I am not kidding. Other provider's mail would often end up in spam or the service would be very confusing. One team, cohesive product, HUMANS! What's not to love. Keep doing what you're doing!

We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!

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

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.
