Still on the fence about switching to Postmark?

Here’s what our customers think of us.

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!

“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”

You go above and beyond to make sure your customers understand transactional email. The educational material you provide make me want to use you. But then there is also the fact (which made me seek you out in the first place) that you take deliverability very seriously. You fixed a problem I had with deliverability in Mandrill. An awesome service.

Unfortunately we didn't have great luck with @SendGrid, using @postmarkapp now & very happy with it.

Every time I integrate @postmarkapp with an app I find myself thinking how great the onboarding is. So refreshing.

Btw, I like @postmarkapp way more than @sendgrid.

...I've been with Postmark for a few months. Their system is definitely better than SendGrid and SparkPost...two services I tried before moving on to Postmark.

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!
