Migration Guides

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

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

BTW @postmarkapp is bloody lovely

Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.

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 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.

Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.

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.

Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun
