What is a BIMI record & how it works

How a domain shows its brand logo in email

BIMI (Brand Indicators for Message Identification) is a DNS standard that lets your brand logo appear next to authenticated messages in supporting mailbox providers. It publishes a TXT record pointing to your logo and, optionally, a certificate that proves you own the mark.

The record lives at default._bimi.example.com and carries an l= tag (the SVG logo URL) and an a= tag (the Verified Mark Certificate). BIMI only takes effect once the domain enforces DMARC, so this tool checks the record, fetches the referenced assets, and validates the logo profile.

l= tag
URL of the brand logo in the SVG Tiny Portable/Secure profile.
a= tag
URL of the Verified Mark Certificate (VMC) proving logo ownership.
Selector
Names which BIMI record to use; almost always “default”.

How to use this tool

Check a domain's BIMI setup in four steps
1
Enter a domain
Type a domain, e.g. example.com — the domain that sends your branded mail.
2
Set the selector
Leave the selector as default unless your provider told you to use another one.
3
Run the lookup
Click Check BIMI Records to read the record and fetch the logo and VMC it references.
4
Review the results
Confirm the logo and certificate resolve, check the SVG profile, and follow the diagnostics and recommendations.

Frequently asked questions

Common questions about BIMI records
5 Q&A

A BIMI record is a TXT record that points mailbox providers to your brand logo (and optionally a Verified Mark Certificate), so your logo can appear beside authenticated messages.

Yes. BIMI requires the domain to enforce a DMARC policy of quarantine or reject with full coverage. Without enforced DMARC, mailbox providers will not display your logo.

BIMI requires an SVG in the SVG Tiny Portable/Secure (SVG Tiny P/S) profile — a square, simplified SVG with no scripts or external references. This tool validates the logo against that profile.

A Verified Mark Certificate (VMC) is an issued certificate proving you own the logo/trademark. Gmail and Apple Mail require a VMC (the a= tag) before they will display the logo.

Common causes are DMARC not being enforced, a missing or invalid VMC (a= tag), a logo that fails the SVG Tiny P/S profile, or the logo/certificate URL not resolving. The diagnostics above pinpoint which applies.
