What is a Sender Score?

Your Sender Score is like a credit score to gauge your credit worthiness but for email: It measures the health of your email program and IP reputation. Each Sender Score is a number between 0 and 100 that identifies the quality of your sender reputation and details how mailbox providers view your IP address.



You need to repair your email reputation. Your IP has been flagged for engaging in risky sending behaviors and your email performance could be suffering because of it.



You have a fine IP reputation score, but there’s room for improvement. Continue to follow industry best practices and optimize your email program.



A history of healthy sending habits has resulted in a great email reputation. Good senders can get recognized and rewarded for their sending — learn more here.
