Level: Advanced
Brand Indicators for Message Identification lets a properly authenticated sender display their verified logo directly in supporting inboxes, a visible trust signal built on top of strong existing authentication.
BIMI Requires a Strong DMARC Foundation First
A domain must have DMARC enforced at quarantine or reject, not just monitoring mode, before BIMI eligibility even becomes possible, since BIMI relies on that underlying authentication strength.
A Verified Mark Certificate Is Required for Full Support
Beyond the DMARC prerequisite, most major providers displaying BIMI logos require a Verified Mark Certificate, a formal, paid verification of trademark ownership tied to the logo being displayed.
It's a Visible Trust Signal, Not a Deliverability Requirement
While not required for standard inbox placement, BIMI adoption has grown as a competitive differentiator, since a verified brand logo next to a message can meaningfully affect recipient trust and open rates.
