Implementing BIMI involves setting up a DMARC policy to 'quarantine' or 'reject,' which is essential for BIMI compliance. For Gmail, a Verified Mark Certificate (VMC) is also necessary, requiring a registered trademark and a verification process handled by a Certificate Authority. VMC issuance includes trademark verification, logo validation, and organizational authentication. The BIMI implementation process and specifications cover record syntax, logo requirements, and security considerations, as outlined by the AuthIndicators Working Group.
