Here’s what our customers think of us.
Can't say enough good things about @postmarkapp. 90 minutes to implement end to end delivery and open tracking.
Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.
Sendgrid was giving us countless problems so we switched over to Postmark and went problem-free!
We've architected our sending infrastructure to rely heavily on Postmark, and we couldn't be happier. They've been supportive at every step along the way, and have helped us to deliver (and report on) tremendous results for our clients.
Postmark ensures that the mail from our customers gets delivered to their customers.
Postmark is superior to SendGrid in every regard.
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!
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.
Been using @postmarkapp for all of 10 mins and it's already clear that it's significantly better than AWS SES.
