Common Mark Certificate (CMC) Product Overview
A Common Mark Certificate, or CMC, is a BIMI certificate for logos that are not registered trademarks but can be validated through prior use. It confirms that an independent authority has verified your rights to use the logo in your BIMI record, even without trademark registration. The BIMI Group explains that both VMCs and CMCs assert that an independent Mark Verifying Authority has confirmed your rights to the mark used in your BIMI logo.
A CMC helps eligible brands show a validated logo in supported inboxes, but it does not provide the Gmail verified checkmark path.

Key Benefits of a CMC
More Accessible Logo Validation
A CMC gives brands a path to BIMI without waiting for trademark registration.
Prior-Use Based Eligibility
The certificate is designed for logos that can be validated through real-world use rather than formal trademark ownership.
Better Brand Visibility
A CMC helps eligible brands show a validated logo in supported inbox experiences.
Lower Complexity than VMC
The BIMI Group explicitly positions CMC as a simpler alternative that reduces cost and effort.
Good Fit for Emerging Brands
CMC can be especially relevant for smaller, growing or newer organizations that want visual trust before trademark registration is complete.
CMCs are a more affordable option than VMCs, making them the perfect entry point for growing brands.
Requirements for a CMC
DMARC Policy
Your domain must have DMARC in enforcement (p=quarantine or p=reject). SPF and DKIM must also be correctly configured.
Proof of Logo Use
CMC eligibility typically requires that the exact logo appears on the current website and has been in use for at least 12 months.
Valid SVG Format
BIMI still requires a strict compliant SVG logo as part of the overall setup.
Secure Hosting & DNS Control
Your hosted assets and BIMI record must be correctly published on a compatible public server.
Who Should Choose a CMC?
A CMC is best for brands that are eligible through prior use and want a lower-friction path to BIMI.
- Brands whose logo is not yet trademarked
- Teams that can prove the logo has been used consistently on their website
- Organizations that want to launch BIMI sooner rather than wait for trademark registration
- Smaller or emerging brands that want a more accessible certificate path
- Businesses that value faster qualification and simpler rollout
CMC vs VMC

VMC (Verified Mark Certificate):
