VMC

A VMC (Verified Mark Certificate) is a certificate issued by an approved BIMI Mark Verifying Authority — currently CAs such as DigiCert, GlobalSign, and SSL.com — attesting that you own the trademark on the logo you want to display via BIMI. Most major mailbox providers require a valid VMC before they will render your BIMI logo. It is the email equivalent of an extended-validation badge for your brand mark.
