BIMI Inspector
Check a domain's BIMI record, fetch the logo and validate it against the SVG Tiny PS profile — plus VMC certificate presence.
BIMI (Brand Indicators for Message Identification) is the standard that puts your logo next to your emails in Gmail, Apple Mail, Yahoo and a growing list of clients. It is a small DNS record — default._bimi.yourdomain — pointing at an SVG logo, but it comes with unusually strict requirements, and a record that almost meets them is simply ignored without any error message.
The first requirement is not technical but organizational: BIMI only activates for domains whose DMARC policy is at enforcement, meaning p=quarantine or p=reject. This is deliberate — a logo in the inbox is a trust signal, so the standard requires proof that the domain cannot be trivially spoofed. If you are still at p=none, fix that first; the logo will not appear regardless of how perfect the rest of the setup is.
The second is the logo format: SVG Tiny PS, a locked-down SVG profile. No scripts, no external references, no embedded raster images, a title element, and the baseProfile="tiny-ps" attribute. Ordinary SVG exports from design tools fail several of these by default. This inspector fetches your actual logo file over HTTPS and runs the profile checks, telling you exactly which requirement fails instead of leaving you guessing.
Finally there is the VMC — the Verified Mark Certificate referenced by the a= tag. Gmail requires one before showing the logo (it involves a registered trademark and a paid certificate from DigiCert or Entrust), while some providers show BIMI logos without it. The inspector reports whether a VMC is referenced so you know which inboxes your logo can currently appear in.
