Spam Score

Spam score is a rating email providers assign to a message to estimate how likely it is to be spam, affecting deliverability.

A spam score is an internal rating email providers and spam filters assign to an incoming message, based on factors like subject line, content, sender reputation, and technical authentication. The higher the score, the higher the odds a message lands in spam.

Common triggers include excessive capitalization, too many exclamation marks, suspicious links, or missing SPF/DKIM authentication. Writing thoughtfully and sending through correctly configured infrastructure keeps your spam score low.
