Brand Indicators for Message Identification (BIMI) is an emerging email specification designed to enhance email authentication and brand recognition within supporting email clients. BIMI leverages the existing DMARC protocol, ensuring that email messages pass DMARC authentication checks before displaying brand-controlled logos. Additionally, BIMI relies on the foundation laid by SPF and DKIM protocols, requiring successful SPF and DKIM authentication to validate the sender’s domain and the integrity of the message content. By connecting BIMI with DMARC, SPF, and DKIM, the protocol aims to provide a comprehensive solution for preventing domain impersonation, improving email security, and enhancing brand identification in the inbox.
