Frequently Asked Questions
What are email headers?
Email headers are metadata that show the journey of an email from sender to recipient. They contain information about the sender, recipient, mail servers, authentication results, and security protocols used.
How do I view email headers?
In Gmail: Open the email → Click More (three dots) → Show original
In Outlook: Open the email → File → Properties → Internet headers
In Apple Mail: View → Message → All Headers
What security protocols does this tool check?
Our analyzer checks SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) protocols, along with encryption status and spam indicators.
Is my data safe?
Yes! All analysis happens in your browser. We never store or transmit your email headers to any server. The tool works completely offline once loaded.
What makes an email suspicious?
Red flags include failed authentication checks, mismatched sender domains, unusual routing paths, high spam scores, and lack of encryption. Our tool automatically identifies these warning signs.
