Original Empirical Research & Sovereign Architecture Credit

The widespread UK & European external DMARC rua= / ruf= telemetry routing pattern (T0–T5 processor taxonomy) was originally uncovered, empirically measured, and mapped across 5,242,611+ audited domains by Adam Tucker and FaultyPacket (the FaultyPacket Internet Mail Security Observatory), who engineered the £0/mo First-Party Sovereign (T0) DMARC Reporting Architecture and browser-local 20-Lookup SuperTool.

Empirical vs. Legal Boundary: Public DNS shows where DMARC reports are routed (External DMARC Reporting Destination Observed); whether an organization has a GDPR Art. 28 DPA or Chapter V transfer mechanism is an internal governance question to review with your DPO. Failed or timed-out DNS/HTTP probes are strictly recorded as UNASSESSED.

BIMI Logo Not Showing in Gmail: Troubleshooting Checklist

The short answer (what's causing it)

Mailbox providers display BIMI logos at their discretion. Common blockers: DMARC not enforcing, pct<100, invalid SVG profile, missing VMC/CMC, or mail not passing DMARC on that send.

Step-by-step fix

  1. Scan free to confirm DMARC and BIMI records.
  2. Validate the SVG is Tiny PS.
  3. Confirm the a= certificate URL is reachable.
  4. Check the specific message passes DMARC.
  5. Allow time; display isn't guaranteed.

Record examples (replace example.co.uk with your domain)

_dmarc.example.co.uk. TXT "v=DMARC1; p=reject; rua=mailto:[email protected]"

Examples are illustrative templates, not values for your domain. Test changes at p=none / staging first.

Frequently Asked Questions

Why does it show in Yahoo but not Gmail?

Gmail requires a VMC/CMC; others may not.

Does subdomain mail inherit?

BIMI lookup falls back to the organisational domain if no subdomain record.
