We looked into sendgrid and also went with mailgun. Been with them for over a year now. Originally started with their mailing list API but had enough service delay problems that we were considering switching entirely. Don't remember exactly but may have had some outages as well. Their support suggested we change to using their batch sending API instead and I'm glad we stuck with them because it's been solid for over 5 months now. (Well they did just have two issues recently, ssl cert and duplicated email sending but it didn't affect us too much.)

Overall they've been a good service provider and their tech support has always been helpful and pleasant to deal with. (I know! Crazy, right?).
