Common Mark Certificate (CMC)
Display your brand logo in email inboxes without a registered trademark. CMC makes BIMI accessible to every organization — from startups to nonprofits to growing brands.
What Is a Common Mark Certificate?
A Common Mark Certificate (CMC) is a digital certificate that verifies your organization's identity and associates it with your brand logo for the BIMI email standard. Unlike a VMC, a CMC does not require a registered trademark — making it the accessible entry point for BIMI.
CMC validates your organization through standard identity verification (similar to an OV SSL certificate) rather than trademark verification. This means startups, nonprofits, educational institutions, and small businesses can all participate in BIMI without the cost and time of trademark registration.
Who Is CMC For?
CMC is ideal for organizations that want BIMI brand visibility but don't yet have a registered trademark.
Startups
New companies building brand recognition before trademark registration.
Nonprofits
Organizations that may not invest in trademark protection but need email trust.
Small Businesses
Local and regional businesses sending transactional and marketing emails.
Education
Universities and schools protecting student and parent communications.
CMC Certificate Benefits

Improve Email Engagement
Brand logos in inboxes increase recognition and trust, leading to better open and click-through rates.
Strengthen Email Security
CMC requires DMARC enforcement, which blocks spoofing and phishing — protecting your brand and recipients.
Build Brand Visibility
Your logo appears alongside every email, reinforcing brand presence even before messages are opened.
Pathway to VMC
Start with CMC today and upgrade to VMC when your trademark is registered for broader inbox support.
Growing Support
CMC support is expanding across email clients. Early adoption positions your brand for full BIMI coverage as it scales.
Current CMC Support
