Overview
SpamChecker analyzes every email you open in Gmail and gives you an instant danger rating — so you know whether to trust a message before you click anything.
Gmail's built-in spam filter works at the server level and gives you no visibility into why a message looks suspicious. SpamChecker fills that gap by running a deep local analysis on every email you open, right in your browser. Nothing is ever sent to external servers.
What SpamChecker checks:
Email authentication — SPF, DKIM, and DMARC pass/fail status
Sender analysis — From/Reply-To mismatches, domain spoofing signals
Routing analysis — hop count, unusual relay paths, origin country
Body analysis — phishing language, suspicious links, URL manipulation tactics
Attachment analysis — dangerous file types, macro-enabled documents, disguised extensions
What you see:
A Danger rating from 1–25 with a clear LOW / MODERATE / HIGH verdict
Top risk factors as readable labels with hover explanations
Origin country of the email
SpamChecker Pro unlocks full forensic detail — complete header breakdown, hop-by-hop trace, auth results, signal scoring, and body preview.
EML file analysis is included free — drag and drop any exported .eml file for the same full analysis outside of Gmail.
All analysis runs locally in your browser. No email content is transmitted or stored.
