Look up default._bimi, the SVG logo, the VMC, and whether DMARC is actually enforcing.
Almost always default. Host becomes default._bimi.domain
BIMI puts a brand mark next to the message in a handful of inboxes. It does not move Gmail placement. You need DMARC at quarantine or reject first, an SVG Tiny P/S logo on HTTPS, and a VMC if Gmail is the point.
Check DMARC on the same domain with the DMARC checker. Build the TXT with the BIMI generator.
Build default._bimi from a logo URL and optional VMC.
BIMI will not display until p= is quarantine or reject.
Brand Indicators for Message Identification. If DMARC is enforcing and you publish a BIMI TXT, supporting inboxes can show your logo next to the message. It is optional. It does not improve placement by itself.
A TXT at default._bimi.yourdomain.com, unless you use another selector. The l= tag is an HTTPS URL to an SVG logo. The a= tag is an HTTPS URL to a Verified Mark Certificate.
Yes. Gmail will not show the logo without a Verified Mark Certificate at a=. Yahoo, La Poste, and some others can show a logo without one. A VMC is a paid certificate from a handful of CAs, not something this tool mints.
The logo is a trust badge. Inbox providers will not put it on mail unless you have a DMARC policy that actually handles unauthenticated mail. p=none is not enough.
SVG Tiny Portable/Secure: square, usually under 32KB, solid background, no scripts or external images. A normal marketing SVG often fails. Convert it specifically for BIMI.
No. The record can be perfect and Gmail still hide it without a VMC. The sending domain, From domain, and DMARC alignment also have to match.
A logo in the inbox is optional. A free audit covers authentication and sending habits.
