About email spam scoring
Spam filters weigh many signals; content is one you fully control. Trigger phrases, ALL-CAPS subject lines, excessive punctuation, heavy link or image ratios, and missing unsubscribe language all push mail toward the spam folder — regardless of how good your authentication is.
This checker applies well-known content heuristics (SpamAssassin-style) to give a quick 0-10 risk score and specific fixes. It analyses content only, in your browser; combine a low spam score with strong SPF, DKIM, DMARC and a clean sending reputation for the best inbox placement.

How does the spam score work?
It scans your subject and body for well-known spam signals — trigger phrases, ALL-CAPS, excessive punctuation, link and image ratios, missing unsubscribe — and returns a 0-10 risk score with the triggered rules.
Is a lower or higher score better?
Lower is better. A score under 2 is low risk; 5 or above is high risk and likely to be filtered.
Does this guarantee inbox delivery?
No. Content is one factor. Even clean content needs strong SPF, DKIM, DMARC and sender reputation to reach the inbox reliably.
Is my email content uploaded?
The content analysis runs entirely in your browser. Only if you click "Improve with AI" is the text sent to the AI service for rewrite suggestions.
What are common spam triggers?
Phrases like "free", "act now" and "guarantee", ALL-CAPS subject lines, lots of exclamation marks, heavy links or images, and missing unsubscribe language.
Can it check HTML emails?
Yes. Paste HTML or plain text; it detects image-heavy content and other HTML-related signals.
