The BIMI (Brand Indicators for Message Identification) specification is an email standard that enables email inboxes to display a brand's logo next to authenticated email messages from trusted senders. It aims to give brands control over how their logos are represented in messaging services, improving security and making it easier for subscribers to identify legitimate messages. To implement BIMI, brands need to set up DMARC compliance, create a BIMI logo image, and update their DNS with the BIMI TXT record. While some inbox providers like Gmail support BIMI, others may require verified mark certificates (VMCs) or have limitations in displaying logos. Brands can check for BIMI readiness using lookup tools and verify their implementation by checking for a BIMI record and logo certification.
