Email Spam Score Checker
Paste your email subject + body, score against common spam triggers (words, ALL CAPS, exclamation, link density).
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.
