Migration Guides

I had no luck with Sendgrid support when I needed it, compared to Postmark support which was super helpful.

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.

“Our experience with the Postmark team has been fantastic. Our emails are sent on time and deliverability is high. We know we can rely on Postmark.”

We used to get complaints about emails ending up in spam.  After switching to Postmark we’ve had zero issues with that.  Really reduced our headaches.

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 !

Postmark has much better deliverability, an amazing dashboard with really good insights.

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

...I love the new templates feature in postmark, BTW! that’s already saving me some time. Look nice too.

...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.
