About VMC and BIMI readiness

A VMC (Verified Mark Certificate) proves you own a trademarked logo and is required by major mailbox providers before they show your BIMI logo. Before applying, your domain must enforce DMARC (p=quarantine or p=reject) and publish a valid BIMI record pointing to an SVG logo.

This checker verifies those prerequisites in order so you fix the real blocker first. Reach DMARC enforcement, publish the BIMI record and logo, obtain the VMC, then reference it with the a= tag.

FREQUENTLY ASKED QUESTIONS

Got Questions? We Have Answers.

What is a VMC?

A Verified Mark Certificate proves you own a trademarked logo. Mailbox providers like Gmail require it before displaying your BIMI logo.

What are the prerequisites for a VMC?

DMARC enforced at p=quarantine or p=reject, a valid BIMI record pointing to an SVG P/S logo over HTTPS, and a trademarked logo you can certify.

Why must DMARC be enforced first?

BIMI only applies to authenticated mail. Providers require DMARC at quarantine or reject so the logo cannot be attached to spoofed messages.

Can I get BIMI without a VMC?

Some providers show logos without one, but the major ones (including Gmail) require a VMC. For broad display, plan on obtaining a VMC.

Does this check my live setup?

Yes. It resolves your DMARC and BIMI records over DNS-over-HTTPS and reports exactly which prerequisite is missing.

What do I do once I am ready?

Apply for a VMC from an authorised provider, then reference the certificate in your BIMI record with the a= tag.
