BIMI Mark Certificate for established brands without a registered trademark.

What is a Common Mark Certificate (CMC)?

A CMC is a BIMI Mark Certificate that validates a brand's established public use of its logo — without requiring a registered trademark. Instead of trademark registration, the CA verifies that your mark has been consistently used in commerce and is publicly recognizable. This opens BIMI logo display to a much wider range of brands that have built strong recognition but haven't completed formal trademark registration.

Questions

Frequently asked questions

What's the difference between CMC and VMC?
VMC requires a registered trademark logo. CMC validates established public use instead — no trademark registration needed. Both produce BIMI-compatible logo display in supporting inboxes.
What proof of "established use" do I need?
SSL.com will ask for evidence of your brand's consistent use in commerce — marketing materials, business registration, web presence, and similar documentation showing established brand use over time.
Which inboxes support CMC for BIMI?
Gmail and Google Workspace support CMC. Other inboxes supporting BIMI (Apple Mail, Yahoo Mail, Fastmail) are also compatible. BIMI adoption across providers continues to grow.
Do I still need DMARC?
Yes — all BIMI logo display requires strict DMARC enforcement (quarantine or reject) on your sending domain. Ensure DMARC, DKIM, and SPF are all in place before ordering a CMC.
Should I get a VMC instead if I have a trademark?
Yes — if you have an active registered trademark, a VMC is the stronger option and is specifically designed for trademarked logos. Use a CMC only if you do not have a registered trademark.
