What is Return Path Sender Score?

Your Sender Score is like a bank running your credit score to gauge your credit history but measures the health of your email program. Sender Score is a number between 0 and 100 that identifies your sender reputation and shows you how mailbox providers view your IP address.

Mailbox providers take a lot of metrics into consideration to determine your sender reputation including spam complaints, mailing to unknown users, industry blacklists, and more.
