Here’s what our customers think of us.
Every time I integrate @postmarkapp with an app I find myself thinking how great the onboarding is. So refreshing.
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.
Wow, @gmail deliveries via @postmarkapp is really fast, ~1s! Seems to have an excellent #ISP reputation. #transactional #mails #service
Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.
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.
We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!
OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.
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.
Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.
