BIMI Inspector
What it is: the hosted BIMI flow: DMARCS holds your logo and certificate, publishes the DNS on your behalf, and continuously checks whether it's actually live.
How to use it: pick a domain, then upload your Logo (SVG only, max 2MB) and, if you have one, your VMC Certificate (PEM only, max 512KB). Both are sanitized server-side: the SVG has any script tags, event handlers, or external references stripped for safety. Click Publish Record (disabled until a logo is uploaded); DMARCS gives you a single CNAME to add (default._bimi pointing at a DMARCS-hosted target) and takes care of the rest.
What the status badge means:
- Live & Protecting (green): your CNAME resolves and the live record is genuinely correct.
- Pending CNAME (amber): published on DMARCS's side, just waiting on your CNAME to propagate.
- Could not verify (amber): the DNS check itself failed (a network/resolver issue); this does not mean BIMI is broken, just that DMARCS couldn't check right now.
- Not Detected (gray): nothing published yet.
An Inbox Preview panel shows roughly how your logo will look next to a sample email, for a quick visual sanity check.
General BIMI requirements, independent of DMARCS: DMARC at enforcement (
quarantine or
reject), an SVG Tiny PS logo, and, for Gmail and some other providers, a VMC. See
Troubleshooting for the exact error messages if an upload is rejected.
BIMI Builder
What it is: the manual, DIY path for organizations that already host their own logo and certificate and want to publish BIMI in their own DNS rather than through DMARCS's hosted flow. Unlike BIMI Inspector, this tool takes URLs, not file uploads.
How to use it: enter your Domain, your Logo URL (a direct link to your hosted SVG), and optionally your VMC URL (a direct link to your hosted certificate). DMARCS builds the exact record live as you type: v=BIMI1; l={logoUrl}; a={certUrl};. Click Check for Conflicts to compare it against whatever's already published at default._bimi.{domain} before you touch DNS.
This tool only advises: it shows you the record and flags conflicts, but you publish it yourself with your DNS provider. It doesn't write DNS for you the way BIMI Inspector's hosted flow does.
VMC Tracker
What it is: a 5-step checklist tracking your Verified Mark Certificate through its lifecycle, so a BIMI logo never silently stops showing when a certificate quietly expires.
What you'll see: a completion percentage and progress bar across five steps: Trademark Verified, DMARC Enforcement, SVG Logo Ready, Purchase VMC, and Publish BIMI. Two of the five (DMARC Enforcement and Publish BIMI) are checked automatically against your live DNS; the other three you mark done yourself as you complete them.
Why use it: BIMI has several moving parts across different tools and a paid certificate with its own renewal date; this page is the single place to see how close you are to having it all correctly in place.
