BIMI (Brand Indicators for Message Identification) is a DNS-published standard that lets participating mailbox providers show your logo beside messages from your domain. It is a reward for good authentication rather than a security control.
Why it matters
A visible logo can improve recognition and trust in a crowded inbox. To qualify, the domain must pass DMARC with an enforcing policy (quarantine or reject), and the logo must be an SVG in the Tiny PS profile. Some providers, including Gmail, also require a Verified Mark Certificate (VMC) or a similar mark certificate proving trademark ownership before showing the logo; support varies, so check each provider's current documentation.
Example
default._bimi.example.com. 3600 IN TXT "v=BIMI1; l=https://example.com/brand/logo.svg; a=https://example.com/brand/vmc.pem"l is the HTTPS URL of the SVG logo and a is the optional certificate. default is the selector; the record lives under _bimi.
Common mistakes
- Starting with BIMI while the DMARC policy is still
p=none. - Using an ordinary SVG export, which usually fails the Tiny PS profile.
- Serving the logo over HTTP or from a URL that redirects or requires login.
- Expecting it to work in every client. Support is provider by provider.
