Great deliverability without upgrading to dedicated IP. Some providers say it can’t be done. We disagree.

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

I came from Mailgun and left because too many emails went missing. Now, my email shows up instantly for people and the amount of time I save on support requests is worth it. A+ quality service.

On top of all the tracking info, in almost four years with Postmark, I can’t remember a single time an outage impacted our business.

👉 @postmarkapp is one of those services that you really enjoy using even if it's a very simple service. Everything feels "right" 👏

Been using @postmarkapp for all of 10 mins and it's already clear that it's significantly better than AWS SES.

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