BIMI Record Checker

Check the BIMI TXT record and its logo/certificate declarations.

BIMI (Brand Indicators for Message Identification) is a standard for displaying a sender brand's logo next to authenticated mail. This tool queries the TXT record at selector._bimi.domain in real time and checks whether the v=BIMI1 declaration, the logo tag (l) and the VMC certificate tag (a) are correctly configured.

Just enter a domain and a selector (default if unsure). If the record exists, the declared logo SVG URL is shown as a preview, and any VMC (Verified Mark Certificate) URL is listed alongside it. Lookups go to a public DNS resolver over DNS over HTTPS, and results are briefly cached.

Anatomy of a BIMI record

A BIMI record is a TXT record at selector._bimi.domain, typically of the form: v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem

v=BIMI1: the BIMI version identifier (required)
l: the URL of the logo SVG to display (an SVG Tiny PS profile is recommended)
a: the URL of a VMC (or CMC) certificate, required by Gmail, Apple and others

Prerequisites for BIMI to work

For a BIMI logo to actually appear, the domain must first enforce DMARC with an enforcing policy (p=quarantine or p=reject) (check the policy with DMARC Record Lookup), and SPF/DKIM alignment must pass. Many mail clients (notably Gmail and Apple Mail) also require a VMC, so you must declare a VMC issued after trademark registration in the a tag.

Logo file requirements

The logo must be a square (1:1) SVG conforming to the SVG Tiny Portable/Secure (SVG P/S) profile. It must be a static SVG with no scripts or external references, and be reachable over HTTPS.

Frequently asked questions

My logo isn't showing. What should I check?

A BIMI record alone is not enough. Verify that DMARC is enforced at quarantine or reject, that SPF/DKIM alignment passes, and that a VMC required by Gmail, Apple and others is declared in the a tag.

What is the selector?

It is a label that lets you run multiple BIMI records. Most domains use the value default, in which case the record lives at default._bimi.domain.

Can I use BIMI without a VMC?

Some mailbox providers display a logo without a VMC, but major clients like Gmail and Apple Mail require a VMC (or CMC). For broad display, obtaining a VMC is effectively required.

Does this tool store the domain I enter?

No. The lookup only queries a public DNS resolver and does not store your input. Results are temporarily cached for 60 seconds for speed.
