BIMI Without a VMC: How Self-Asserted BIMI and CMCs Actually Work
You can publish BIMI without a VMC. Self-asserted BIMI shows your logo in Yahoo, AOL and Fastmail with no certificate at all. A Common Mark Certificate adds Gmail logo display without a registered trademark. A Verified Mark Certificate is the only path to the Gmail blue checkmark. This guide gives you a clear decision map, the record syntax, and the DMARC prerequisites every path shares.
