BIMI setup requires these key components:

1. Email Authentication Requirements:

• Fully implemented and passing DMARC validation

• DMARC policy must be set to either:

  • "quarantine" with 100% policy (pct=100)

  • OR "reject"

• This applies to both your sending domain and organizational domain (if different)

2. BIMI DNS Record:

• Must publish a valid BIMI record in your DNS

• Record should point to:

  • Your logo in SVG format (meeting BIMI specifications)

  • A Verified Mark Certificate (VMC) if required by receiving mailbox providers
