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
Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun
A superior transactional email service, with unmatched customer support
My customers are so confident in their transactional email now, that they no longer include 'check in your spam box' in their website messaging anymore. Account email confirmations and missing invoices are a thing off the past. The activity feed gives myself and my customers total confidence in using email for important tasks again.
Ok, clearly I hate SendGrid. PostMark 5x better.
Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.
I highly recommend @postmarkapp for transactional email. Dedicated to delivery, great help docs, and a clear and simple UI.
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!
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.
