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

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 !

I am baffled that anyone would choose Sendgrid over Postmark. If they tried both, they probably wouldn’t. Delivery rates are just night and day honestly!

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.

Ok, clearly I hate SendGrid. PostMark 5x better.

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.

Postmark makes it easy for us to handle all our outbound emails with a high degree of reliability and easy way to get insights into what messages are working with our customers (via tags and analytics).
