BIMI logo not displayed
Supporting inboxes do not show the BIMI brand indicator.
Problem summary
Supporting inboxes do not show the BIMI brand indicator.
Symptoms
- BIMI DNS published but logo absent in supporting clients
- Inspectors warn about DMARC or certificate requirements
- Some providers show BIMI; others never will without VMC
Possible causes
- DMARC not at required enforcement
- Missing/invalid VMC where required
- SVG profile issues
- Provider does not support BIMI for that mailbox type
How to diagnose
- Validate DMARC policy strength for BIMI targets
- Check default._bimi and logo URL fetch
- Run a BIMI inspector; note certificate requirements
How to fix
- Meet DMARC enforcement prerequisites first
- Fix SVG/certificate issues
- Set expectations: BIMI is best-effort per provider
How to verify
- Inspector reports no hard DNS/SVG errors
- Spot-check a known supporting client when prerequisites are met
Prevention
- Treat BIMI as a follow-on to solid DMARC, not a substitute
- Track provider BIMI requirements separately
When to escalate
- Production mail is failing for a material share of recipients after remediation attempts
