What is BIMI and why does it drive open rates?
Brand Indicators for Message Identification (BIMI) allows authenticated senders to display their verified brand logo directly next to incoming messages in recipient inboxes. In Gmail, BIMI also powers the verified blue checkmark.
BIMI increases open rates by 15–28% because recipients immediately recognize legitimate corporate communications versus fraudulent phishing spoofing.
Prerequisites for BIMI Verification
- 1. DMARC at Strict Enforcement: Your DMARC policy must be p=reject or p=quarantine with pct=100.
- 2. SVG Tiny P.S. Logo: The logo must be formatted according to the strict SVG Tiny 1.2 Portable/Secure profile without external links or scripts.
- 3. Verified Mark Certificate (VMC) or Common Mark Certificate (CMC): Issued by a trusted certificate authority (DigiCert or Entrust) verifying trademark ownership.
