To display a BIMI logo in Yahoo Mail, you must meet several requirements. Strong DMARC enforcement (p=quarantine or p=reject) is essential, along with a valid Verified Mark Certificate (VMC) to prove logo ownership. A positive sender reputation, based on consistent sending practices, high engagement, and low spam complaints, is also critical. Yahoo considers historical performance, infrastructure setup, and has less transparent reputation criteria. Technical requirements for DNS records and logo formatting must be followed, and VMC must be from an approved Certificate Authority. Consistent monitoring and proactive adjustments are needed to maintain BIMI.
