What else can I say about Sendgrid? It's the single best SMTP service; it's a fabulous service if your architecture is already in the cloud; it's cheap; the people are great.

I would recommend against SendGrid. We started using SendGrid using a relative old list. We immediately ran into issues with this list and had our account suspended. Checking the same list with MailChimp we found that MailChimp warned us about the quality issues before sending, allowing us to clean the list, and SendGrid just closed our account after sending and running into high bounce rates. After that we had to deal with a highly critical customer service department that treated us like a headmaster treats a child. Contrastingly, working with MailChimp is a breeze. I realize that using an old list was actually a mistake on our side. However, I believe a service can protect you against making beginner's mistakes in stead of punishing you for them.
