What this isn't: a real SpamAssassin run — that requires sending and grading. This is a rule-based heuristic covering the patterns Gmail / Outlook / Apple Mail's filters consistently flag. Pair with Mail Tester or Litmus for production deliverability testing.

About this tool

Quick heuristic spam scoring based on the same rules ESPs and SpamAssassin use, trigger words ('free', 'guarantee', 'act now'), excessive caps, link density, image-to-text ratio, multiple exclamation marks.

What this tool isn't

A rule-based heuristic, not a real-time SpamAssassin / Microsoft SCL score. For production deliverability testing, send to Mail Tester or Litmus. But for catching obvious issues before send — wrong from address, ALL CAPS subject, spam-trigger words — this catches 80% of issues at zero cost.
