Frequently Asked Questions

What are email spam trigger words? +
Spam trigger words are phrases that email spam filters are trained to flag. Common examples include "free", "guaranteed", "act now", "click here", and "make money". Too many of these send your email to the junk folder.
How is the spam score calculated? +
The spam score is based on the number and density of trigger words found. 0 flagged = Low Risk (green). 1–3 flagged = Medium Risk (yellow). 4+ flagged = High Risk (red). Actual deliverability also depends on sender reputation and domain health.
Should I check the subject line or the full email body? +
Both. Subject lines are checked first by filters and are the highest risk. But spam words in the body also hurt your overall spam score. Check each separately for best results.
How many spam words does this tool detect? +
This tool scans for 100+ spam trigger words commonly flagged by Gmail, Outlook, Yahoo Mail, and SpamAssassin — the most widely used email spam filter in the world.
Is my email content private? +
Yes, 100% private. All scanning happens in your browser using JavaScript. Your email content is never sent to any server or stored anywhere.
