What this email spam checker does
Before a campaign or an important cold email goes out, it is worth scanning the copy the way a spam filter would. This checker scores the content signals filters weigh: a dictionary of several dozen trigger phrases, the ratio of capital letters, exclamation-mark density, the balance of links to real text, and thin-content patterns. Everything is analyzed live in your browser — your draft is never uploaded.
The score is deliberately conservative: passing here does not promise the inbox, but failing here means you are handing filters easy reasons to be suspicious.
How to check your email for spam signals
- Paste the email body into the box.
- Review each finding — errors are strong signals, warnings are cumulative ones.
- Rewrite flagged phrases in plainer language and rebalance links vs. text.
- Re-check until the score sits comfortably above 80.
Fixing flagged copy without losing the message
Most trigger phrases have neutral equivalents: “free” becomes “at no charge”, “act now” becomes a specific deadline, “click here” becomes a descriptive link like “see the March pricing”. Specific, concrete language both reads better and scores better. Don’t forget the subject line — test it separately with the Email Subject Line Tester.
