Here’s what our customers think of us.
We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.
A superior transactional email service, with unmatched customer support
Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.
“Postmark really impressed us with their focus on transactional emails, instead of just broadcasting.”
Sendgrid was giving us countless problems so we switched over to Postmark and went problem-free!
We use @postmarkapp. Incredibly reliable service run by incredible people.
...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.
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.
I've tried several of the competitors and finally found Postmark. What a relief to find a straightforward integration for our PHP-based client websites. Setting up was a breeze, the clean and easy to learn UI was enjoyable, and the confidence knowing that web form submission made it to the client? Priceless. Thanks, Postmark, for helping me go from scared and frustrated to confidence in our communication components.
