Migration Guides

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

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

Postmark has been incredibly easy to use, is unfailingly fast and reliable, and the Wildbit team is always around for fast, efficient help.

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.

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.

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!

You have an excellent user interface and very good spam reputation service. Combined with the pay-what-you-use subscription a better alternative to Mailchimp and its expensive Mandrill moneymaking machine.

Made the switch to @postmarkapp today. The customer service and delivery rates are awesome, but the thing I love is EVERYTHING IS YELLOW!

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 !
