Start with DMARC, not the SVG
BIMI is built on an authenticated domain identity. If DMARC is absent or not at an enforcement posture expected by the ecosystem, perfect logo artwork will not solve the readiness problem. Evaluate the domain policy before debugging the visual asset.
Parse the BIMI record as configuration
The default BIMI TXT record can point to a logo location and, depending on the deployment, authority evidence. Validate that the record is syntactically coherent and that the referenced resources use appropriate secure URLs. A DNS record is necessary configuration, not a guarantee that every mailbox will display the logo.
Mailbox providers control final presentation
Provider participation and certificate requirements differ. Some environments may require a verified mark certificate or another accepted credential. Treat “readiness” as the structural prerequisites under your control and “display” as a separate provider decision.
Keep logo and certificate lifecycle in the audit
BIMI is not a one-time publish-and-forget project. Logo hosting, certificate expiration, DNS policy and DMARC enforcement can change. Include these resources in the same change-monitoring discipline used for email authentication.
Verify the evidence
Use the live analysis that matches this workflow instead of relying on a generic status check.
