A rating predicting how likely your email is to be flagged as spam.
Understanding Spam Score
Spam score is a rating that predicts how likely your email is to be filtered as spam by email providers. Various tools calculate spam scores by analyzing factors that spam filters use: content triggers (spammy words, excessive caps, misleading subject lines), technical issues (missing authentication, blacklisted domains), and sending patterns.
Common spam triggers include: phrases like "free," "urgent," or "act now" in excess; all-caps text; too many images relative to text; broken links; purchased email lists; and poor sender authentication. Tools like Mail Tester, SpamAssassin, and email platform built-in checkers can score your emails before sending. Keep spam scores low by following best practices: authenticate your domain, maintain list hygiene, write naturally, and send to engaged recipients.
