What Is a Common Mark Certificate (CMC)?
A Common Mark Certificate (CMC) is a digital certificate which cryptographically binds the verified brand logo to your domain. It is issued by a certification authority (CA) after strict verification.
When paired with a BIMI record and DMARC enforcement, a CMC shows your logo directly in the inbox beside your sender’s name in Gmail and Yahoo Mail. This visual trust signal blocks impersonation attacks, builds brand credibility, and lifts engagement.
