Email client support for BIMI
Understanding which email clients support BIMI is crucial for maximizing your brand’s logo visibility and trust. This article breaks down the latest BIMI adoption landscape, highlights key requirements by provider, and offers practical tips for ensuring consistent inbox display.
What Is BIMI?
BIMI (Brand Indicators for Message Identification) enables verified logos to appear alongside authenticated emails in supported inboxes. To leverage BIMI, brands must meet strict authentication and logo requirements; however, support depends on the recipient’s email client and provider.
Major Email Clients and BIMI Support
Gmail
- Comprehensive Support: Full support for desktop, web, and mobile Gmail apps ensures broad brand visibility.
- Strict Requirements: Requires DMARC enforcement (p=quarantine or p=reject at 100%) and a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC).
- Brand Trust Indicator: Gmail adds a blue checkmark for VMC-verified brands, signifying verified identity and authenticity.
Yahoo Mail
- Full Platform Support: Available on both webmail and mobile apps for consistent brand presence.
- Strict DMARC Requirement: Requires DMARC set to “p=reject” and references the BIMI record and logo for authentication.
- VMC Encouraged: A Verified Mark Certificate (VMC) is optional but recommended for enhanced verified logo display.
Apple Mail (iOS, iPadOS, macOS)
- BIMI Support Across Apple Devices: Available for users on iOS 16+, iPadOS 16+, and macOS Ventura 13+.

Tips for Maximizing BIMI Logo Display
How to Implement BIMI
- Prioritize Authentication: DMARC enforcement (p=reject/quarantine), proper SPF/DKIM, and a BIMI-compliant SVG logo are required everywhere.
- Obtain a VMC/CMC: Increases compatibility and adds trust signals on Gmail and Apple platforms.
- Monitor Provider Updates: Email client support continues to expand—track announcements from your major audience’s providers.
- Test with Real Accounts: Send test emails to different providers and devices for hands-on validation and to ensure proper logo display and deliverability.
Common Pitfalls and How to Avoid Them
- Assumptions and Compatibility: Assuming all clients support BIMI - always consult up-to-date compatibility guides.
- VMC Certificate Omission: Omitting a VMC certificate limits logo display on providers like Gmail and Apple.
- Common Pitfalls: Outdated SVG logos or inconsistent DMARC policies may result in failed or missing logos.
