## Frequently Asked Questions
What is an email header?
An email header contains technical details about the email's journey, including sender information, routing data, timestamps, authentication results, and spam scores.
How do I view email headers?
In Gmail, click the three dots next to the reply button and select "Show original." In Outlook, open the message and click File > Properties > Internet headers.
What can I learn from email headers?
Email headers reveal the message's path through different servers, SPF/DKIM/DMARC authentication status, IP addresses of sending servers, and potential signs of spoofing or spam.
Can email headers be forged?
Some header fields can be forged, but authentication records like SPF, DKIM, and DMARC help verify the legitimacy of emails. Received headers added by mail servers are difficult to forge.
Is the email header analyzer secure?
Yes, our tool processes headers in real-time without storing any data. However, avoid sharing headers containing sensitive information in public forums.
