Best Practices for BIMI

To properly implement BIMI, first reinforce your email authentication, prepare your logo and VMC, then publish and maintain the necessary DNS records. Below are detailed guidelines (before, during, and after implementation) to help you set up BIMI and have your business logo displayed in recipient inboxes.

Before Implementation

Strengthen Authentication

• Enable SPF, DKIM, and DMARC.
• Set DMARC to p=quarantine or p=reject.
• Use DMARC reports to find and fix issues.

Prepare Your Logo

• Use a high-quality, trademarked logo.
• Export as a compliant SVG (typically 64x64–256x256).
• Keep the design simple, high-contrast, and recognizable at small sizes.

Obtain a VMC

• Purchase a Verified Mark Certificate (VMC) from a trusted Mark Verifying Authority (MVA).
• Required for logo display in most inboxes.

During and After Implementation

Publish BIMI DNS

• Add BIMI DNS records pointing to your logo and VMC.

Test

• Verify logo display across major email clients.
• Use our free BIMI Record Check tool to routinely test your setup.

Monitor and Maintain

• Continuously monitor SPF/DKIM/DMARC for compliance.
• Review BIMI and DNS settings regularly.
• Renew your VMC annually.
• Troubleshoot BIMI issues.

Support Deliverability and Trust

• Use a reputable email service provider (e.g., Gmail, Outlook, Yahoo! Mail).
• Avoid "dark patterns": don't over-email, and keep unsubscribes easy and clear.
