BIMI

Brand Indicators for Message Identification (BIMI) is a fresh and hot off the press email standard which makes it possible for companies to use their brand within email clients that support BIMI. BIMI provides a nice way to gain more brand visibility and to some extent also help protect users against impersonation.

BIMI relies heavily on preexisting standards such as SPF, DKIM and DMARC. BIMI logos will not displayed for letters that do not align with DMARC. DMARC deployment is a prerequisite for BIMI. After all, one of the goals of BIMI is to reduce impersonation.

BIMI is also supported by most large providers, such as Apple Mail, Google Gmail/Gsuite and Yahoo. You can find a full list of vendors that support BIMI here.

Technical requirements

BIMI requires a “strict” DMARC policy, letters that do not align with the policy must be quarantined (p=quarantine) or rejected (p=reject). DMARC must be enforced for all letters, the pct value must not be below 100(%).

Additional information

You can find instructions on how to set up DMARC here.

Because BIMI does increase trust in the sender’s authenticity, most providers require a VMC certificate. Same goes for Zone Webmail. You can find more information about BIMI for senders, including VMCs here.

Zone Webmail will display BIMI graphics only if the logo comes with a Verified Mark Certificate (VMC) and passes all of BIMI standard’s requirements of authenticity. Meaning that the letter must align with the domain’s DMARC.

BIMI looks like this in our Webmail:
