How to Set Up BIMI (Brand Indicator)

BIMI shows your verified brand logo in supported inbox UIs — Gmail, Apple Mail, Yahoo. It's a trust signal that sets your mail apart from generic placeholder avatars. Setup requires DMARC at p=quarantine or p=reject, an SVG Tiny 1.2 logo, and (for Gmail) a Verified Mark Certificate.

Prerequisite: enforce DMARC

BIMI requires DMARC at p=quarantine or p=reject (not p=none). If your DMARC is monitoring-only BIMI will silently fail. See our setup-dmarc guide.

Prepare an SVG Tiny 1.2 logo

BIMI logos must be SVG Tiny 1.2 Portable/Secure profile — square no embedded scripts no external references. Tools like svgcleaner or Adobe Illustrator's SVG Tiny export will produce a valid file.

Host the logo over HTTPS

Upload to https://yourdomain.com/logo.svg (or a CDN). The URL must be reachable must serve image/svg+xml and must not redirect.

Get a Verified Mark Certificate (for Gmail)

Gmail will only display the logo if you have a VMC from DigiCert or Entrust. Cost: $1500-2000/year. The VMC verifies you own the trademark — required for trademark logos. Yahoo and Apple display without VMC.

Publish the BIMI record

Add a TXT record at default._bimi.: v=BIMI1; l=https://yourdomain.com/logo.svg; a=https://yourdomain.com/vmc.pem (omit a= if you don't have a VMC).
