Question 1

How do I verify a forwarded email?

Accepted Answer

Ask the mailbox owner to export the original email as a .eml file, then upload it to selfcheck.email. The DKIM signature on the original indicates whether the content is unchanged.

Question 2

What does DKIM verification establish?

Accepted Answer

A valid DKIM signature establishes that the email content has not been altered since the sender's mail server signed it. It does not establish that the content is true or that a specific person wrote it.

Question 3

Is SelfCheck free?

Accepted Answer

Yes. You can verify up to 5 emails per hour without an account. Free accounts get 5 cases per month with timestamped PDF reports.

Question 4

Does SelfCheck store my email?

Accepted Answer

No. The email file is processed in memory and deleted immediately. Only cryptographic hashes and the PDF report are retained.
