How to certify an email as legal evidence
To certify an email as legal evidence, capture it in webmail with a Browser Session or upload the original .eml source file as a File certificate. The signed PDF binds the message to a qualified RFC 3161 timestamp — much harder to dispute than a forwarded copy or screenshot.

Why a screenshot of an email is not enough.
Email evidence is challenged more often than any other digital evidence type.
✗
Full headers are not visibleDKIM, SPF, SMTP trace, Message-ID — none of these appear in the standard inbox view.
✗
Any word processor can fabricate an email imageCourts know this and weight email screenshots accordingly.
✗
Forwarded copies lose original headersForwarding strips the DKIM signature and original Message-ID.
✗
No independent proof of timingThe "Date" line is your provider's clock, not a qualified timestamp authority.

Email-certification questions.
How do I certify an email so it can be used as legal evidence?
Open the email in webmail and use a Browser Session to capture the page, or save the source .eml file and use a File certificate. Both produce a signed PDF with a qualified RFC 3161 timestamp bound to the content.
Can I prove an email was sent at a specific time and not altered?
Yes. Capture the message in webmail with full headers shown, or upload the .eml source file. The certificate binds the content's SHA-256 hash to an independent timestamp — any later modification breaks the hash.
What if the email was sent from a free webmail provider?
The certification process is identical. Gmail, Outlook, Yahoo, Proton, and others all work — the capture records what the webmail interface displayed at the moment of certification.
Can I certify a forwarded email?
Yes, but note that forwarding strips the original DKIM signature. If the original sender is reachable, request the original message and certify it directly.
Is this legal advice?
No. This service creates technical evidence artifacts. Legal admissibility depends on jurisdiction and circumstances. Consult qualified legal counsel for advice specific to your situation.
