BIMI checker

BIMI is how a domain publishes a logo. Enter a domain to read its default._bimi record and check the version, the logo SVG, and whether a mark certificate is named.

The DNS lookup goes from your browser to Cloudflare. The logo URL, when there is one, is fetched from your browser too. We don’t see either request or store the domain.

What this does not prove

  • That a mailbox will display the logo. Some require a VMC and a mark that matches the certificate.
  • That the SVG meets the BIMI tiny-SVG profile beyond “it is an SVG we could fetch”.
  • That the certificate file is a valid VMC. This check only confirms a= is an https URL.
