What is: Sender Score
A sender score is a metric used by email service providers to measure the reputation of a sender.
The higher the sender score, the more likely an email is to be delivered to the recipient’s inbox. A low sender score can result in emails being sent to spam folders or not being delivered at all.
Sender scores are determined by a variety of factors such as the number of complaints received from recipients, the number of spam reports filed against the sender, and how often emails from the sender are marked as spam.
