Catch spam words before the filters do

Spam filters score every email, and certain words push that score up fast. A subject line stuffed with "free", "guaranteed" and "act now" can sink an otherwise great cold email straight into the junk folder.

This free spam word checker scans your copy against a curated list of common trigger words and phrases, highlights each one, and rates your overall risk — so you can fix problems before you hit send.

Words are only half of deliverability

Clean copy keeps you out of spam, but it won't save you if you're emailing invalid addresses or sending from an unauthenticated domain.

Verify every recipient with Emailchaser's free email verifier to cut your bounce rate and protect your sender reputation — the biggest levers on whether you reach the inbox.

Common questions about spam trigger words

What are email spam trigger words?


Spam trigger words are words and phrases — like "free", "act now", "guaranteed" or "risk-free" — that spam filters associate with junk mail. Using too many of them, especially in your subject line, raises the chance your email is filtered into spam instead of the inbox.

How does the spam word checker work?


Paste your subject line and email body, and the checker highlights every spam trigger word it finds, counts them, and gives you a risk level. Rewrite or remove the flagged words to lower your spam risk before you send.

Will removing spam words stop my emails going to spam?


It helps, but it's only part of the picture. Deliverability also depends on a clean recipient list, authenticated sending domains (SPF, DKIM, DMARC), warmed-up inboxes and low bounce rates. Verify your list and warm your inboxes alongside cleaning up your copy.

Is the spam word checker free?


Yes — it's free, needs no signup, and runs entirely in your browser. The text you paste is never sent to a server.
