Here’s what our customers think of us.
Wow, @gmail deliveries via @postmarkapp is really fast, ~1s! Seems to have an excellent #ISP reputation. #transactional #mails #service
OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.
Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.
Before Postmark we were using SendGrid, but we had lots of problems with the IP reputation, and they wouldn't move us to another IP range. So we decided change providers, and we are very happy with Postmark.
I don't plug products much, but good god damn @postmarkapp has made us very, very happy. An order of magnitude better than running our own mail.
BTW @postmarkapp is bloody lovely
Postmark every day. UX is great. Delivery is top-notch and super fast. I've also used Sparkpost and Mailgun and they just don't compare.
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.
Wow, even after two years of using Postmark I’m still surprised by how much you value your customers!
