Most spam scoring happens inside your sending infrastructure, SpamAssassin, or cloud SMTP provider, and the result is tucked away in an X-Spam-Score header that you would normally only see by inspecting the raw message. LocalMail.dev surfaces that value automatically.
When a spam score header is present, a badge appears next to the email subject. Green means the score is below 2 and the email is likely clean. Amber means the score is between 2 and 5, indicating a moderate risk. Red means the score is above 5 and the email may be filtered or blocked.
Hovering over the badge shows the full X-Spam-Status string so you can see exactly which rules contributed to the score without switching to the headers tab.

Frequently asked questions
How does LocalMail.dev display spam scores?
LocalMail.dev automatically reads the X-Spam-Score and X-Spam-Status headers from each captured email. If the header is present, a colour-coded badge appears next to the email subject. Scores below 2 show green, scores between 2 and 5 show amber, and scores above 5 show red.
Does LocalMail.dev calculate a spam score itself?
No. LocalMail.dev reads the X-Spam-Score header that your sending infrastructure or a spam filter adds to the email. If your SMTP setup does not add spam scoring headers, the badge will not appear. This is by design: LocalMail.dev shows the real score your email already carries.
Which spam score headers does LocalMail.dev support?
LocalMail.dev reads X-Spam-Score for the numeric value and X-Spam-Status for the status string. Both SpamAssassin and many cloud-based SMTP providers add these headers by default. Hovering over the badge shows the full X-Spam-Status value.
