What is BIMI?
Understand what BIMI is, how it works with DMARC, and why it is used for brand visibility in email clients.
What BIMI is
BIMI stands for Brand Indicators for Message Identification. It is a standard that allows eligible senders to publish branding information that some mail clients can use.
BIMI depends on a stronger email authentication posture, especially DMARC enforcement.
How BIMI is published
BIMI is typically published as a TXT record under default._bimi.yourdomain.com.
The record can reference a logo location and, in some cases, a verified mark certificate.
Why BIMI matters
BIMI can help reinforce brand trust and visual recognition in supported mail clients.
It is not a replacement for core authentication controls, but rather a layer built on top of them.
