Here’s what our customers think of us.
Using a completely free product and still getting great support from @postmarkapp. Two days and I haven't heard back from @Mail_Gun
For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.
...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 highly recommend @postmarkapp for transactional email. Dedicated to delivery, great help docs, and a clear and simple UI.
OMG! @postmarkapp is a chef's kiss. Mandrill or SendGrid is never again.
Trying out @postmarkapp for my next react app blog and wow they have much better dev. experience than @SendGrid. Very clear & step-by-step.
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.
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.
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.
