Frequently Asked Questions
What is an email header?
It is the technical metadata behind an email, including routing, sender, server, and authentication information.
Can this detect every phishing email?
No. It highlights risk signals, but users must still inspect links, attachments, and context.
What are SPF, DKIM, and DMARC?
They are email authentication methods that help verify whether a message is authorized by a sending domain.
Does the tool send my email to a server?
The recommended implementation parses the header locally in the browser.
Can forwarded emails look suspicious?
Yes. Forwarding can change routing and authentication results, so the summary should explain uncertainty.
