Where to find it
Select DNS Tools in the left navigation, then the BIMI Scanner tab. Enter a domain and select Check BIMI. The tool looks for a TXT record atdefault._bimi.yourdomain.com.
No BIMI record found
If nothing is published, the result names the exact address it checked and lists what BIMI requires:1
Reach an enforcing DMARC policy
BIMI only applies once DMARC is set to
p=quarantine or p=reject. Monitoring-only is not enough. Use the DMARC Configurator to move your policy up.2
Create an SVG Tiny PS logo
BIMI accepts one format: SVG Tiny Portable/Secure. An ordinary SVG export will not validate.
3
Obtain a VMC certificate
A Verified Mark Certificate proves you hold the trademark on the logo. Gmail requires one before it will display your logo.
4
Publish the record
Add a TXT record at
default._bimi.yourdomain.com pointing to your logo, and to your certificate if you have one.
