Myth: Email authentication needs the body and attachments. Reality: Hush Line Email Validation works with Raw Email Headers to inspect DKIM, SPF, and DMARC. Recipient teams can leave the contents in place. Headers may expose addresses and delivery paths, so protect them too.

Light-mode Hush Line social graphic titled “Validate headers without copying the email body.” A desktop Tools screenshot shows Email Validation with a Raw Email Headers field, Validate Headers, Download Report, and a Validation Summary saying the email appears to originate from the stated sender. The graphic contrasts the myth that the whole email is required with the reality that the tool uses its headers.
