Common Spam Word Checker Use Cases
Spam word scanning is useful for any email campaign, sequence, or transactional message.
Marketing campaigns — scan email copy before scheduling to maximize inbox placement
Sales outreach — check cold email sequences for words that trigger spam filters
Newsletter editing — audit new issue content for trigger words before sending
Transactional email review — check notification templates for spam language

How to Read Spam Word Results
Understanding the score and flagged words helps you target your rewrites effectively.
Check Your Spam Score
The score ranges from 0 to 100. Low (0–25) is acceptable. Medium (26–60) suggests rewrites. High (61–100) means the email will very likely land in spam — rewrite before sending.
Review Flagged Words by Category
Money words (free, cash, earn $) carry heavy weights. Urgency words (act now, limited time) are frequently flagged. Scam patterns (guaranteed, no risk, you've won) score highest with most filters.
Focus on the Subject Line First
Subject line spam words have more impact than body words. Spam filters weight the subject heavily. Removing one high-risk subject word often improves inbox placement more than rewriting an entire body paragraph.
Rewrite and Re-scan
After rewriting flagged terms, paste the new version back and scan again. Aim for a score below 25 before sending. Pair spam word checking with a full email test including SPF, DKIM, and DMARC validation.

Frequently Asked Questions
What are spam trigger words?
Spam trigger words are terms and phrases that spam filters associate with unsolicited or deceptive email. Categories include money language (free, earn $, guaranteed), urgency language (act now, limited time, don't miss out), and scam patterns (you've won, no risk, click here).
How does the spam score work?
The spam score ranges from 0 to 100. A score of 0–25 is low risk. A score of 26–60 is medium risk and suggests rewrites. A score above 60 is high risk and indicates the email is likely to be filtered to spam by major inbox providers.
Should I remove all flagged words?
Not necessarily. Context matters — spam filters use machine learning alongside keyword lists. Remove the highest-weight flagged terms first, especially from the subject line. Reducing overall word count and score below 25 is a practical target.
Is the subject line more important than the body?
Yes. Spam filters weight the subject line more heavily than the body. A single high-risk word in the subject (like 'FREE' in all caps) can flip inbox placement to spam even when the body is clean.
Does this tool test actual spam filter behavior?
No. This tool scans against a static spam trigger word database. Actual spam filter decisions use machine learning, sender reputation, engagement history, and dozens of additional signals. Use this tool alongside SPF, DKIM, and DMARC validation for a complete pre-send check.
What is the difference between spam words and spam content?
Spam words are trigger terms in the text. Spam content includes additional signals like image-to-text ratio, link density, HTML formatting issues, and sender reputation. This tool checks for word-level triggers only.
How can I reduce my spam score?
Replace flagged money and urgency words with neutral alternatives. Avoid ALL CAPS and excessive punctuation (!!!). Remove high-weight scam pattern phrases. Re-scan after each revision until the score drops below 25.
Does this tool store my email content?
No. Your subject and body text are analyzed in real time and not stored or retained after the check completes.
