What this spam word checker does

This tool scans your email body against a hand-curated list of 145 words and phrases that commercial spam filters commonly flag. Paste any text — a newsletter draft, an outreach email, or a message you received — and the tool highlights every match, assigns a weighted risk score, and shows you exactly which triggers appeared and how often.

How the score works

✦ Each trigger has a severity (low, medium, high, critical).

✦ Matches are weighted: critical triggers count 4x, high 3x, etc.

✦ The weighted score is normalised against message length.

✦ Score ranges: 0–14 Low, 15–39 Medium, 40–69 High, 70–100 Critical.

Why this matters for deliverability

✦ Spam filters score every word and phrase in your email.

✦ High trigger density increases the chance of inbox placement failure.

✦ Tone down exaggerated claims and urgency language for better results.

✦ A low score here is not a guarantee — filters also check reputation, auth, and engagement.

Clearing the filter is step one. Getting a reply is step two.

NeatMail tracks what you sent and never heard back on, files it under one Follow up label with a date, and drafts the nudge when it's time — so a delivered email doesn't quietly die unanswered.

About the Spam Trigger Word Checker

A spam trigger word checker is a tool that scans your email copy for words and phrases known to raise spam-filter suspicion — like "free," "act now," "guarantee," and "risk-free" — and returns a spam score with each match highlighted. It helps marketers and senders rewrite risky wording before sending, improving the odds an email reaches the inbox rather than the spam folder.

Frequently asked questions

What are spam trigger words?
Spam trigger words are terms and phrases that filters associate with junk or scam email, such as "free money," "100% guaranteed," and "urgent," along with excessive punctuation or all caps. Using several of them raises the chance an email is filtered, though no single word guarantees a block.
Do trigger words alone send email to spam?
No. Modern filters weigh many signals — sender authentication (SPF, DKIM, DMARC), domain reputation, engagement, and content — not just wording. Trigger words contribute to a score, so reducing them helps, but strong authentication and list hygiene matter more.
How do I lower my spam score?
Cut salesy trigger phrases, avoid all caps and rows of exclamation marks, keep a balanced text-to-image ratio, include a real unsubscribe link, and send from an authenticated domain. Writing naturally and relevantly for the reader is the most reliable fix.
Is my email content stored?
No. The text you paste is analyzed in your browser and is not uploaded or saved, so you can safely check drafts that contain confidential or unpublished content.
