Check DMARC and BIMI readiness for any domain
Validate whether a domain is ready for stronger email trust signals. This checker reviews DMARC posture, BIMI DNS records, logo requirements, and certificate readiness from one page.
DMARC posture
Policy presence, enforcement, alignment, and reporting checks.
BIMI record quality
Record syntax, version tags, logo tags, and certificate pointers.
Hosted asset validation
HTTPS reachability, SVG constraints, and VMC-related checks.

Guidance
How to use the results
Work through the highest-risk gaps first, then the supporting improvements.
Why it matters
BIMI depends on a strong email authentication foundation. If DMARC is missing, weak, or not enforced, branded logos in the inbox become much harder to support safely.
What to fix first
Failed checks usually point to missing records, unreachable assets, or invalid syntax. Warnings often indicate a usable setup that still falls short of recommended enforcement or presentation standards.
Best next step
Start with DMARC enforcement and record validity, then move to BIMI asset quality, hosted SVG compliance, and certificate matching checks.
Continuous monitoring and visualisation
Talk to JSsecJSsec provides ongoing DMARC monitoring and reporting visualisation so you can track policy enforcement, alignment trends, and failure sources over time, not just at point-in-time checks.
