Brand Indicators for Message Identification, or BIMI (/ˈbɪmi/), is a specification allowing for the display of brand logos next to authenticated e-mails.
There are two parts to BIMI: a method for domain owners to publish the location of their indicators, and a means for Mail Transfer Agents (MTAs) to verify the authenticity of the indicator.[1][2]
To implement BIMI, companies need a valid DMARCDNS record with a policy of either quarantine or reject, an exact square logo for the brand in SVG Tiny P/S format,[3] and a DNS TXT record for the domain indicating the URI location of the SVG file. The only supported transport for the SVG URI is HTTPS.[1] The BIMI DNS record is in the following format:
Additionally, services such as Gmail require that a Verified Mark Certificate (VMC) be acquired and presented with the TXT record in order for the brand logo to be displayed in the inbox.[4] These factors alone will not guarantee a BIMI logo will be displayed as heuristics (like spam and spoofing) and reputation will be a key part in BIMI validity.[5]
To query the value of the default._bimi TXT record for a given domain, one can use the Dig command-line tool. For example, the following command will query the TXT record for the example.com domain: dig +short default._bimi.example.com TXT.
