Frequently asked questions

What do I need for BIMI?

DMARC at enforcement (p=quarantine or p=reject, with pct=100 and no sp=none), a square SVG Tiny Portable/Secure (SVG Tiny PS) logo served over HTTPS, and for Gmail and Apple Mail a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC).

Where is the BIMI record published?

As a TXT record at default._bimi.yourdomain (or another selector), for example v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem.

Which mailboxes show BIMI logos?

Gmail, Apple Mail, Yahoo Mail, AOL and Fastmail, among others. Gmail requires a VMC or CMC; Yahoo can show logos without a certificate for senders with good reputation.
