Here’s what our customers think of us.
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.
Super customer support, on-boarding process especially incredible. Service 10/10. Struggled with other services like Mailgun — never again. Keep being awesome.
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 has stellar customer service. I don't think I have ever waited more than a few minutes for a response to an email. I also like the degree of interest that the representatives take in my specific circumstances. I felt like they took the time to really understand what I needed and then proposed the best solution for me.
Password reset emails delivered by @postmarkapp arrive in gmail in 1 second (vs 64 seconds for SendGrid)
I came from Mailgun, which gave me headaches. Every second counts when we send an alert to gamers. I love the fact that I can see when mails are opened and how long the whole process took. It just works, which is not so obvious apparently (looking at Mailgun). Thanks Postmark Team <3 !
Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.
We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.
