Short answer

A Verified Mark Certificate (VMC) is a digital certificate proving a brand owns its trademarked logo, required by Gmail and others to show that logo via BIMI. Certificate authorities issue VMCs after verifying the trademark. Together with DMARC enforcement, it allows a verified brand logo to appear beside messages in supporting inboxes.
