Absolutely abysmal support. I had a critical non-delivery issue with one of my client websites and it took SendGrid 25 DAYS TO SEND THE INITIAL CONFIRMATION for that high priority ticket, and it was just to ask if I still needed help. Support is obviously not important to them. Obviously, I had plenty of opportunity to shop around, so I have moved to Postmark -- the service and support have been absolutely amazing and my only regret is that I didn't choose Postmark in the first place.
