Put your verified logo in every inbox
Mark Certificates work with BIMI and DMARC to display your authenticated brand logo or official seal next to the sender name — before your email is even opened. Three certificate types cover every organization, from global enterprises to government agencies.
Compare Mark Certificates
Three Mark Certificate types serve every organization — from private companies with registered trademarks to government agencies with official seals. Compare features below to find the right certificate for your brand.
✶ Yahoo Mail: Yahoo does not currently require a Mark Certificate for BIMI logos to appear in Yahoo applications. However, if a BIMI record includes a VMC, Yahoo will use it to inform overall BIMI eligibility.
