Email Spam Word Checker

What is Email spam word checker?

Spam Word Checker — Check your copy against 45 spam trigger words before you hit send: paste any subject or body text and see flagged terms with severity ratings.

This is a pattern linter, not a live spam-filter test: it matches your text against a bundled, curated list of 45 spam-trigger words and phrases in 6 categories (urgency, money, deceptive, pressure, shady, common), using case-insensitive whole-word matching. Risk is low by default, medium with any medium-severity match or 2+ matches, and high with any high-severity match or 6+ matches. Real mailbox filters are behavioral and ML-based — sender reputation, authentication, and engagement — and cannot be tested from a browser, so treat this as a writing aid, not a deliverability guarantee.

Good to know

Pattern linter only — NOT a live spam-filter test; it cannot predict inbox placement.
Matches against a bundled 45-term curated list; real filters use far more signals.
Severity ratings and risk thresholds are heuristic writing guidance, not measured filter behavior.
Word-boundary matching means some variants (misspellings, leetspeak, curly apostrophes) will not match.
Text longer than 5000 characters is truncated with a visible notice.
