What it is
BIMI (Brand Indicators for Message Identification) is a DNS record that lets supporting inboxes show your brand logo next to messages from your domain. Gmail, Yahoo, Apple Mail and several other providers display it for mail that passes DMARC.
BIMI works only on top of strong email authentication: your DMARC policy must be quarantine or reject. Gmail and Apple Mail also require a mark certificate that proves your right to the logo: a Verified Mark Certificate (VMC), which needs a registered trademark, or for Gmail a Common Mark Certificate (CMC). getReport checks for a BIMI record at default._bimi.yourdomain. It is optional; set it up after DMARC is enforced.
What a passing site looks like
- BIMI publishes a logo for your mailinfo onlyeffort L
No BIMI record, so inboxes show no logo for your mail
Why it matters. BIMI shows your logo in supporting inboxes, which lifts recognition and trust. It needs DMARC at quarantine or reject first, and Gmail and Apple Mail also need a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC).
- Reach p=quarantine or p=reject first, then publish default._bimi.yourdomain with v=BIMI1; l=https URL of an SVG Tiny PS logo.
Questions people ask
What is a BIMI record?
It is a TXT record at default._bimi.example.com, for example v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem. l points to your logo in SVG Tiny PS format and a to your mark certificate, and both files must be served over HTTPS. Without a certificate, some providers, such as Yahoo, can still show the logo for senders with a good reputation.
What are the BIMI logo requirements?
The logo must be an SVG file in the SVG Tiny Portable/Secure (SVG Tiny PS) profile: square, with a solid background, and without scripts or external links. It should still look right when cropped to a circle. Standard SVG exports from design tools usually need converting. For a VMC, the logo must match your registered trademark.
Do I need a certificate for BIMI?
For Gmail and Apple Mail, yes. You need a Verified Mark Certificate, which requires a registered trademark, or for Gmail a Common Mark Certificate, which requires the logo to have been in public use for at least a year. Both are issued by a small number of certificate authorities, such as DigiCert and Sectigo, and are renewed and paid for every year.
