Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.

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.

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

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

Had a horrific experience with SendGrid so i would avoid. We use Postmark and are very happy with it :D

We use Postmark and are very happy with it. Switched from SendGrid due to security problems, dodgy UI, and not storing email content.
