For a BIMI logo to appear, you need: DMARC at p=quarantine or p=reject (enforcement is mandatory), a correctly formatted SVG Tiny PS logo over HTTPS, a valid default._bimi record, and for Gmail/Apple a Verified Mark Certificate (VMC) referenced in the a= tag.
No enforcement, no logo — BIMI requires DMARC at quarantine or reject first. The logo must be SVG Tiny Portable/Secure, square, and hosted over HTTPS. Most major mailboxes (Gmail, Apple Mail) also require a VMC proving you own the trademark.
A PNG instead of SVG, a non-square logo, a missing a= (VMC) tag, or DMARC still on p=none. Fix DMARC enforcement first — it’s the most common blocker.
