Reduce Your SpamAssassin Score

SpamAssassin is not the whole internet, but repeated high scores usually point to issues worth fixing anyway.

Typical score drivers

  • Weak or failing authentication
  • Suspicious wording or formatting
  • Broken MIME structure
  • Too many links or heavy redirect usage
  • Sender infrastructure that looks inconsistent

Practical reduction plan

  1. Fix SPF, DKIM, and DMARC first.
  2. Simplify the message structure.
  3. Remove avoidable shorteners and noisy tracking patterns.
  4. Keep branding and domains consistent.

Do not optimize for SpamAssassin alone. Use it as a proxy for message hygiene, then validate with representative inbox testing.
