Definition
Email spam scoring is how spam filters assign points to an incoming email based on many signals, such as content characteristics, sender reputation, authentication, list behavior and engagement. A high score raises the chance the mail is filtered as spam.
Content 'spammy' patterns (excessive exclamation, spam-trigger words, link-heavy or image-only layouts, irregular formatting) add risk, while authentication, good reputation and clean engagement reduce it. Filters merge these into a single likelihood decision.
You cannot perfectly avoid every trigger, but clean practices keep your score low: send from authenticated, well-reputed domains with clean lists and quality content, and test your emails with spam-checking tools before major sends.

Frequently Asked Questions
It is a measure of how likely a filter considers an email to be spam, computed from content, reputation, authentication and engagement signals.
Excessive punctuation, spam-trigger words, image-only or link-heavy layouts, poor authentication, and sending from low-reputation or unclean sources all raise spam likelihood.
Use authenticated, reputable sending, keep lists clean and permission-based, write quality content, and test with spam-checking tools before sending.
