The BIMI Revolution: Brand Logos in Email Inboxes
BIMI (Brand Indicators for Message Identification) is the new email authentication standard that allows verified brands to display their logos directly in supported email clients, starting with Gmail. This creates immediate brand recognition and builds trust with your subscribers.
Game Changer: BIMI transforms how recipients interact with your emails. Instead of just seeing your name in the inbox, they see your authentic brand logo, significantly increasing engagement and trust.
However, BIMI requires a solid foundation of email authentication and a verified trademark. This guide walks you through the complete BIMI implementation process and how to test your setup with Mail-Score.com's BIMI testing capabilities.
What is BIMI and How Does It Work?
BIMI Explained
BIMI is an email specification that allows organizations to display their brand logo in supporting email clients. It builds upon existing email authentication protocols (DMARC) to verify brand ownership and authenticity.
The BIMI Value Proposition
Displaying your logo creates instant brand recognition, increases email engagement, builds trust with recipients, and helps combat phishing by making legitimate emails easily identifiable.
How BIMI Works in Practice:
- Email is received by a BIMI-supporting client (like Gmail)
- Client checks for BIMI DNS record and validates DMARC policy
- If DMARC passes and BIMI is properly configured, the brand logo is displayed
- Recipient sees authenticated brand logo next to email in inbox
The 5 Essential BIMI Requirements
DMARC Enforcement (p=quarantine or p=reject)
Your domain must have a DMARC policy set to either "quarantine" or "reject" - monitoring mode (p=none) is not sufficient for BIMI implementation.
Required DMARC Policy
Or Stronger Policy
High DMARC Compliance Rate
Your emails must consistently pass DMARC authentication. Most providers require a high percentage (typically 95%+) of emails passing DMARC checks.
Note: You can check your DMARC compliance rate using Mail-Score.com testing, which provides detailed authentication analysis including BIMI readiness.
Verified Trademarked Logo
Your logo must be a registered trademark. For Gmail implementation, you need to work with a certified BIMI verification authority.
Logo Requirements
- SVG format (Scalable Vector Graphics)
- Square aspect ratio (1:1)
- Optimized for small display sizes
- Simple, recognizable design
Verification Process
- Work with approved certification authorities
- Provide trademark documentation
- Submit logo for verification
- Receive VMC (Verified Mark Certificate)
Proper BIMI DNS Record
You must publish a BIMI DNS record that points to your verified logo and includes the location of your VMC (Verified Mark Certificate).
Example BIMI Record:
Consistent Email Authentication
All your email sending sources must be properly authenticated with SPF and/or DKIM, and aligned with your DMARC policy.
Authentication Stack
- SPF records authorizing all sending IPs
- DKIM signatures for all outgoing email
- DMARC policy enforcement
- Consistent From domain usage
Testing Requirement
- Use Mail-Score.com to verify authentication
- Check BIMI readiness status
- Test across all sending platforms
- Monitor ongoing compliance
