They do exactly what they say they are going to do. We use SMTP2GO as our main email provider for critical business emails because I know I can rely on them to just work. I tried a number of providers before settling on SMTP2GO and very happy with my choice. If I ever need to speak to someone, the support is always friendly and helpful.

Honestly, nothing. I had some issues with their pricing structure as I was left on an old legacy plan which meant I was overpaying. Once spotted they quickly offered to refund all the over payments and give me credit for them. Review collected by and hosted on G2.com.
