Am I Eligible for a Common Mark Certificate (CMC)?

Q: Can I replace a CMC with a VMC later without disrupting BIMI?

Yes. The BIMI record's a= tag is simply updated to point to the new VMC URL once it is issued. If the old CMC URL is retired, update the record before taking the CMC offline to avoid any gap in the certificate reference. DNS propagation after the change takes 24–48 hours.

Direct Answer

A CMC does not require a registered trademark. The eligibility requirements are: a domain with DMARC at p=quarantine or p=reject, a logo that meets SVG Tiny PS format requirements, and organizational identity verification by the issuing CA. A CMC enables BIMI logo display in providers that support it — but it does not qualify for the Gmail blue verified checkmark, which requires a VMC backed by a registered trademark.

CMC vs. VMC Eligibility Requirements

VMC — Verified Mark Certificate

Registered trademark at a recognized trademark office
Trademark must match the logo submitted
DMARC at p=quarantine or p=reject
SVG logo in SVG Tiny PS format
Organization identity verification
Enables Gmail blue verified checkmark

CMC — Common Mark Certificate

No registered trademark required
Domain ownership verification
DMARC at p=quarantine or p=reject
SVG logo in SVG Tiny PS format
Organization identity verification
Does not enable Gmail blue verified checkmark

What the CA Verifies for a CMC

Without a trademark to validate, CMC issuance centers on confirming that the applicant organization controls the domain and has a legitimate identity. The CA verifies that the organization exists, that the applicant has authority to act on its behalf, and that the logo submitted does not constitute trademark infringement against a known registered mark. The SVG file is also validated against the SVG Tiny PS specification.

A CMC does not validate trademark ownership. It verifies organizational identity and domain control. Submitting a logo that infringes a registered trademark will result in rejection and potential legal exposure — separate from the CMC process itself.

What a CMC Does and Does Not Enable

Capability	CMC	VMC
BIMI logo display (providers that support CMC)	Yes	Yes
Gmail blue verified checkmark	No	Yes
Yahoo Mail logo display	Yes	Yes
Requires registered trademark	No	Yes
Satisfies `a=` tag requirement in BIMI record	Yes	Yes

Organizations pursuing BIMI without a registered trademark may qualify for a Common Mark Certificate. a CMC provides a path to logo display across supporting providers while a trademark application is in progress. Once the trademark is granted, a VMC can be obtained to unlock Gmail verified checkmark display. See Can I Get BIMI Without a Trademark? for the broader picture.

Frequently Asked Questions

Can I apply for a CMC while my trademark application is pending?

Yes. A CMC does not require a granted trademark — only a VMC does. You can obtain a CMC with a pending trademark application (or no application at all) and switch to a VMC once the trademark is registered. The two certificates are independent; getting a CMC first does not simplify or accelerate VMC issuance later.

Is a CMC cheaper or faster to obtain than a VMC?

CMC issuance does not require trademark validation, which removes one validation track. This can make the process faster and may affect pricing depending on the CA. Organization identity and SVG validation are still required. Compare specific CA offerings for current pricing and estimated timelines.

Can I replace a CMC with a VMC later without disrupting BIMI?

Yes. The BIMI record's a= tag is simply updated to point to the new VMC URL once it is issued. If the old CMC URL is retired, update the record before taking the CMC offline to avoid any gap in the certificate reference. DNS propagation after the change takes 24–48 hours.
