The VMC is the trust anchor: it proves the logo belongs to the trademark holder, preventing brand impersonation in the inbox.
How to implement Verified Mark Certificates (VMC)#
- Confirm your logo is a registered trademark in an accepted jurisdiction (USPTO, EUIPO, UKIPO, JPO, and others).
- Prepare the exact trademarked artwork as SVG Tiny PS.
- Complete organization validation with the CA, including notarized identity verification.
- Receive the PEM certificate, host it over HTTPS, and reference it in the a= tag of your BIMI record.
- Calendar the renewal; VMCs are valid for one year.
How to verify it worked#
Send a test message to seed mailboxes at Gmail, Outlook, and Yahoo, then inspect the Authentication-Results and delivery headers. Repeat after any DNS or sending-platform change.
Common mistakes#
- Submitting a logo that differs from the registered mark, even slightly.
- Letting the certificate expire, which silently removes the logo.
- Assuming a pending trademark application qualifies; it must be registered.
