Which companies use BIMI?

Companies that use Brand Indicators for Message Identification (BIMI) include major global brands such as CNN, Groupon, and Aetna, among others. These businesses follow BIMI requirements to display their verified logo next to authenticated emails, helping improve brand recognition and user trust.

Where is BIMI supported?

BIMI is currently supported by major email providers such as Gmail, Yahoo Mail, Apple Mail (iOS 16 and macOS Ventura or later), and Fastmail. Support may vary by region, but adoption is growing as more providers recognize the security and branding benefits of BIMI.

Is BIMI a form of email authentication?

BIMI isn’t a standalone form of email authentication. BIMI works with existing authentication protocols like Domain-based Message Authentication, Reporting, and Conformance (DMARC), Sender Policy Framework (SPF), and DomainKeys Identified Mail (DKIM). Regarding BIMI requirements, a domain must have a DMARC policy set to quarantine or reject.

Why BIMI email clients matter

BIMI email clients are helping companies strengthen security and boost brand visibility in email inboxes. The number of BIMI email clients is increasing, allowing more businesses to enhance their email marketing impact and deliverability.

Implementing the standard shows your organization’s commitment to security and brand integrity. Ensure your company’s domain meets all authentication requirements, including a DMARC policy of p=quarantine or p=reject. Decide whether to get a VMC for full logo and checkmark display or use a CMC where possible for logo display without the verified checkmark.
