Migration Guides

dunno why but I'm using Resend and the spin up time to actually send an email is diabolical. Sometimes users are waiting 1 min + for a confirmation email. I dunno if it's just free tier things or because I'm based in Canada but I'm not the biggest fan.

Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.

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

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.

Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.

Postmark ensures that the mail from our customers gets delivered to their customers.

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.

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

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.
