What’s Your Sender Score?

Sender Score is a free e-mail reputation service that can provide you with important information you need to safeguard your e-mail reputation and deliverability.

Sender Score allows you to enter an IP address or domain name and get a “Sender Score.” The score is a quantitative indicator of  e-mail reputation. The score is based on the same kinds of data that ISPs like Google and Yahoo use to evaluate email senders –  like the number of complaints you generate, the volume of mail you send, how your process bounces, and if you are on any blacklists.  The Sender Score is based on 100 points.
