Frequently Asked Questions

What is Email Header Privacy Analyzer?

It is a tool that checks your email headers for leaked personal data—such as your real email address or IP addresses—to ensure your alias forwarding remains secure.

How does the analyzer work?

Paste your email headers into the tool, and it uses regular expressions to extract email addresses and IP addresses for analysis.

What information does it scan for?

It scans for email addresses, IP addresses, and "Received:" header lines that may leak routing information.

What is an email header?

An email header is the part of an email that contains detailed information about its transmission, including sender and receiver addresses, routing data, and metadata.

How do I copy an email header?

To copy an email header, open the email, look for the “View Source” or “Show Original” option, then select and copy all the header text that appears.

What happens if my real email address is detected?

If an email address different from your alias is detected, the tool will issue a warning that your real email might be leaking through the header.

Why are IP addresses a concern?

IP addresses can reveal your network and geographical location, suggesting that your original connection details may not be fully masked.

Can I use this tool on mobile devices?

What should I do if warnings appear?

Review any warnings and adjust your alias forwarding settings or consult your privacy documentation for further steps.
