Definition
BIMI (Brand Indicators for Message Identification) displays your brand logo next to authenticated emails in supporting email clients including Yahoo, Gmail, and Apple Mail. It requires DMARC enforcement (p=quarantine or p=reject), a BIMI DNS record, and a Verified Mark Certificate.
Requirements
- DMARC enforcement: Your domain must have DMARC set to p=quarantine or p=reject
- Logo file: A square SVG logo uploaded to a publicly accessible URL
- BIMI DNS record: A TXT record at
default._bimi.yourdomain.com - VMC: A Verified Mark Certificate from an approved certificate authority (required by Gmail, optional for Yahoo)
BIMI DNS Record
default._bimi.yourdomain.com. IN TXT "v=BIMI1; l=https://assets.yourdomain.com/logo.svg; a=https://assets.yourdomain.com/vmc.pem"
Why It Matters
BIMI increases trust and brand recognition in the inbox. Early adopters report 5-15% higher open rates and improved brand recall. It also signals to ISPs that you take authentication seriously, which positively influences deliverability.
Best Practices
- Start with the fundamentals of Email BIMI Setup and build from a clear baseline, so later improvements are measurable rather than assumed.
- Keep Email BIMI Setup consistent with how the rest of your email programme works, so no single initiative works against another.
- Review how Email BIMI Setup is handled in your own data and adjust from what you see, rather than copying what another brand does.
- Test one change at a time and measure the effect before rolling it out more widely.
- Revisit your approach to Email BIMI Setup regularly, because audience behaviour and inbox technology keep moving.
- Make sure the basics — relevance, timing, and honesty — are solid before chasing more advanced tactics.
