BIMI (Brand Indicators for Message Identification)

BIMI lets organizations that have implemented DMARC display their official brand logo alongside delivered emails in supporting email clients (including Gmail, Apple Mail, and Yahoo Mail).

Prerequisites for BIMI

To qualify for BIMI:

DMARC Enforcement: Your domain must have an active DMARC policy of either p=quarantine (with pct=100) or p=reject.
SVG Logo Format: Your logo must be formatted as an SVG Tiny P/S file according to official BIMI specifications.
Verified Mark Certificate (VMC): Certain mailbox providers (such as Gmail) require a VMC issued by a recognized certificate authority (DigiCert, Entrust).

DNS Configuration

Once your SVG logo and certificate are hosted publicly over HTTPS, publish the following DNS TXT record at default._bimi.yourdomain.com:

v=BIMI1; l=https://yourdomain.com/bimi-logo.svg; a=https://yourdomain.com/vmc-certificate.pem;
