Gmail to show your company logo in inbox if DMARC and BIMI authenticated

After first announcing Gmail’s Brand Indicators for Message Identification (BIMI) pilot last year, today we’re announcing that over the coming weeks we’re rolling out Gmail’s general support of BIMI, an industry standard that aims to drive adoption of strong sender authentication for the entire email ecosystem

BIMI enables organizations that authenticate their emails using Domain-based Message Authentication, Reporting, and Conformance (DMARC)—a standard for providing strong sender authentication that allows security systems to perform better filtering, separating legitimate messages from potentially spoofed ones—to validate ownership of their logos and securely transmit them to Google. BIMI is designed to be easy: for organizations with DMARC in place, validated logos display on authenticated emails from their domains and subdomains.

Here’s how it works: Organizations who authenticate their emails using Sender Policy Framework (SPF) or Domain Keys Identified Mail (DKIM) and deploy DMARC can provide their validated trademarked logos to Google via a Verified Mark Certificate (VMC). BIMI leverages Mark Verifying Authorities, like Certification Authorities, to verify logo ownership and provide proof of verification in a VMC. Once these authenticated emails pass our other anti-abuse checks, Gmail will start displaying the logo in the existing avatar slot.

For logo validation, BIMI is starting by supporting the validation of trademarked logos, since they are a common target of impersonation. Today, Entrust and DigiCert support BIMI as Certification Authorities, and in the future the BIMI working group expects this list of supporting validation authorities to expand further. To learn more about BIMI and see the latest news, visit the working group’s website.

To take advantage of BIMI, ensure that your organization has adopted DMARC, and that you have validated your logo with a VMC
