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

I’ve used SendGrid, Mandrill and Postmark for transactional email in production. Amazing how much better Postmark is than everyone else.

Postmark has been incredibly easy to use, is unfailingly fast and reliable, and the Wildbit team is always around for fast, efficient help.

Made the switch to @postmarkapp today. The customer service and delivery rates are awesome, but the thing I love is EVERYTHING IS YELLOW!

Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.

...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.

We‘ve grown from sending 0 to 200,000 transactional emails daily, and Postmark helped us a lot with scaling that process.
