      What the score means

      The score adds up content signals that spam filters and human readers both react to: known trigger phrases, links, capital letters, exclamation marks, money and percentage claims, length, and whether the email opens with a first name. Under 25 is clean. 25 to 44 is borderline. 45 and up usually lands in spam on a cold domain.

      What it does not measure

      Content is one of three things a mailbox provider looks at. The other two, sender reputation and sending behaviour, are not visible from a draft. A perfect score on a burned domain still goes to spam. If your copy is clean and you are still filtered, check the domain and check the volume.

      The phrases we flag

      Strong triggers (red) are words almost never found in a real one-to-one email: guaranteed, risk-free, click here, act now, winner, 100% free. Mild triggers (yellow) are fine once but add up: free, discount, amazing, following up. The list is maintained by hand from cold email that actually landed in spam, not copied from a marketing blog.

      Questions

      Does a spam word checker guarantee inbox placement?

      No. Content is one of three signals. Domain reputation and sending behaviour matter more once your copy is clean. Use the checker to remove avoidable triggers, then check your domain setup.

      Is my email stored?

      No. The checker runs entirely in your browser. The text never reaches our server.

      What is a good spam score for cold email?

      Under 25 on this tool. Between 25 and 44 is borderline and depends on your domain reputation. 45 or more usually goes to spam on a new or cold domain.

      Why is "free" flagged when I see it in newsletters?

      Newsletters go to people who opted in, on warmed domains with high engagement. Cold email has none of that, so filters weigh the same word more heavily.
