BIMI deployment is not a one-time event — it is a system that requires ongoing maintenance across 5 distinct health dimensions. An organisation that deployed BIMI 18 months ago and has not reviewed it since may believe it is “done.” The data suggests otherwise.
59.8% of all active global BIMI certificates are more than 365 days old — in the renewal risk zone where upcoming expiry creates operational jeopardy if not actively managed. The average certificate age globally is 585 days, more than 19 months. 32.8% of certificates are older than two full years, meaning they have already been through at least one renewal cycle — and may be approaching another.
This report introduces the VMCcerts BIMI Health Score Framework: 5 measurable dimensions of BIMI deployment health that any organisation can assess against their own deployment. It also provides the dataset benchmarks that allow organisations to position their health score against the global peer population.
The Framework
5 Dimensions of BIMI Deployment Health
A healthy BIMI deployment requires ongoing attention across 5 areas. Each dimension can be assessed independently, and each carries different risk profiles depending on the organisation’s sector, CA, and sending volume.
Section 01
Certificate Age Distribution — The Global Renewal Risk Picture
| Age Range | Certificates | % of Total | Status | Action Required |
|---|---|---|---|---|
| 0–3 months | 2341 | 11.6% | Fresh | No action — monitor DMARC policy drift |
| 3–6 months | 2212 | 10.9% | Healthy | Routine check — flag for 6-month review |
| 6–12 months | 3575 | 17.7% | Watch zone | Plan renewal — initiate process 90 days before expiry |
| 12–18 months | 3104 | 15.3% | Risk zone | Immediate renewal review — most are near or past expiry |
| 18–24 months | 2357 | 11.7% | High risk | Verify certificate is still valid — check expiry date now |
| >24 months | 6638 | 32.8% | Critical audit | Audit required — these have been through 1–2 renewals; verify all 5 dimensions |
6638 active global BIMI certificates are older than 24 months. These organisations have maintained BIMI through at least one complete renewal cycle — which is positive. But they are also the most likely to have accumulated health drift: outdated PEM URLs in DNS, trademark renewals not checked, logo files migrated without BIMI SVG validation. A full 5-dimension health audit is warranted for any certificate older than 24 months.
Section 02
The BIMI Health Score — How to Calculate Yours
| Dimension | Max Points | Full Score Criteria | Zero Score Criteria |
|---|---|---|---|
| D1 · DMARC Enforcement | 20 | p=reject on all sending domains | p=none or missing on any domain |
| D2 · Certificate Currency | 20 | >90 days to expiry, renewal process active | Expired or <30 days without renewal initiated |
| D3 · Trademark Health | 20 | Trademark active, expiry >12 months, monitored | Trademark lapsed or unmonitored |
| D4 · Logo File Integrity | 20 | BIMI SVG accessible, validated, spec-compliant | File inaccessible or non-compliant |
| D5 · DNS Record Accuracy | 20 | PEM URL current, DNS propagated, mailbox-verified | Stale PEM URL, DNS mismatch |
| Score Range | Status | Recommended Action |
|---|---|---|
| 80–100 | Optimal | Maintain monitoring cadence — quarterly full review |
| 60–79 | Healthy | Address any non-full-score dimension within 30 days |
| 40–59 | Moderate | One or more dimensions at risk — escalate to owner within 2 weeks |
| 20–39 | At Risk | Multiple failures — immediate audit and remediation |
| 0–19 | Critical | BIMI likely broken — emergency review, possible logo already gone |
Section 03
The Next 6 Months — 3814 Certificates at Expiry Risk
45.9% of all active global BIMI certificates — 3814 organisations — face certificate expiry between June and November 2026. This is not a forecast: these are certificates whose metadata confirms expiry within six months of the dataset snapshot date.
If your certificate expires in the next six months and you have not initiated renewal, begin immediately. The minimum lead time from renewal initiation to successful DNS propagation is typically 7–14 business days. For organisations with complex trademark portfolios or regulated IT change processes, allow 30–60 days minimum.
90 days before expiry: initiate renewal with CA and verify trademark health. 60 days before: submit renewal application with trademark documentation. 30 days before: receive new certificate, prepare DNS update. On renewal day: update BIMI DNS TXT record with new PEM URL, propagate, validate with BIMI inspector tool within 24 hours.
Expert Interpretation
The average 585-day cert age tells a story of organisations that deployed and stopped managing
19 months is the average age of an active BIMI certificate as of 2026-07-02. That is more than a full renewal cycle for most CAs. The organisations at 12+ months did not all successfully renew — many have drifted into silent failure: an expired certificate they believe is still working, a DNS record pointing to a PEM URL that is no longer valid, or a logo file that was moved during a website migration without anyone thinking to check the BIMI reference.
Silent failure is BIMI’s most underreported risk
An expired BIMI certificate does not generate an error message that reaches the email marketing team. Recipients simply stop seeing the verified logo. Open rates may decline marginally. No alert fires. For weeks or months, the organisation believes its BIMI is working while recipients see it is not. The only way to detect silent failure is proactive monitoring — running a BIMI lookup tool against your own sending domain on a fixed schedule.
D3 (trademark health) and D4 (logo file integrity) are the two most commonly neglected dimensions
Certificate renewal gets calendar reminders. DNS updates get IT tickets. DMARC policies get quarterly security reviews. But trademark renewal dates are owned by legal and rarely shared with the marketing or IT team managing BIMI. And logo file integrity checks are never performed unless there is a website migration — and even then, BIMI is rarely on the migration checklist. These two dimensions are where healthy deployments decay silently.
