BIMI Record Lookup & Validator
Enter a domain to fetch its BIMI record from default._bimi.<domain>. The tool validates the logo URL and Verified Mark Certificate (VMC) so you can confirm your brand logo is ready to display in Gmail and Yahoo Mail.
What is a BIMI record?
BIMI (Brand Indicators for Message Identification) is a DNS-based standard that lets a domain publish a brand logo which supporting inboxes display next to authenticated messages. The record lives in a TXT entry at default._bimi.<domain> and points to a hosted logo and, optionally, a certificate that proves you own the mark.
What does a BIMI record require?
A valid BIMI record needs three things to display a logo in Gmail and Yahoo: a passing DMARC policy at enforcement, an HTTPS-hosted SVG logo, and a Verified Mark Certificate. Each prerequisite builds on the previous one.
- DMARC at enforcement - your domain must have a DMARC policy of
p=quarantineorp=reject(notp=none). - HTTPS SVG logo - the
l=tag must reference an SVG over HTTPS, encoded as SVG Tiny Portable/Secure (SVG Tiny PS). - Verified Mark Certificate (VMC) - the
a=tag references a VMC. Gmail and Yahoo require a VMC before they will render the logo. - Square, centred artwork - the logo should be a 1:1 square with the mark centred so it renders cleanly as an avatar.
- Published at the default selector - the standard selector is
default, giving the record namedefault._bimi.<domain>.
How do I read the tags in a BIMI record?
A BIMI record is a short, semicolon-separated tag string. The three tags you will see are the version, the logo location, and the certificate location.
v=BIMI1- the version identifier; it must be exactlyBIMI1.l=- the HTTPS URL of the SVG logo. An emptyl=explicitly declines logo display.a=- the HTTPS URL of the VMC (a PEM file). Without it, most mailbox providers will not show the logo.
Why is my BIMI logo not showing?
The most common reasons a BIMI logo fails to display are a DMARC policy still at p=none, a missing or non-compliant VMC, or a logo that is not valid SVG Tiny PS. Mailbox providers silently skip the logo rather than show an error, so validating the record is the quickest way to find the gap.
Frequently asked questions
Is BIMI required for email delivery?
No. BIMI is purely a branding and trust signal. It does not affect whether your mail is delivered, but it can improve recognition and open rates once DMARC is enforced.
Do I need a VMC to use BIMI?
Gmail and Yahoo require a Verified Mark Certificate before displaying a logo. Some other providers will show an unauthenticated logo from the l= tag alone, but a VMC is the safe, broadly supported path.
What logo format does BIMI use?
BIMI requires SVG Tiny Portable/Secure (SVG Tiny PS) - a restricted SVG profile that strips scripts and external references. A normal exported SVG usually needs to be converted before it will validate.
What selector does BIMI use?
The default selector is default, so the record is published at default._bimi.<domain>. Custom selectors are possible but rarely used; this tool checks the default selector.
How this tool works: This tool runs in your browser and on our server in real time. Depending on the tool, results are computed directly from the input you provide or retrieved from live, authoritative data sources at the moment you run a lookup. We do not sell your data, and your lookups are kept private — any history shown here is stored only on your device.
