- Add the HTTPS URL of your logo — BIMI can't do anything without it.
- Without a VMC (a=), Gmail and Apple Mail won't show your logo. Yahoo and Fastmail may still display it. The VMC is a paid Verified Mark Certificate from a certificate authority.
- BIMI requires DMARC at enforcement first — a published policy of p=quarantine or p=reject (with pct=100). Set that up before BIMI will take effect.
Before BIMI will work
- DMARC at enforcement. You need a published DMARC policy of
p=quarantineorp=rejectatpct=100. This is the hard prerequisite. - An SVG Tiny PS logo over HTTPS. Square, with a solid background — and specifically the SVG Tiny PS profile, not a regular SVG.
- A VMC, for Gmail and Apple Mail.A Verified Mark Certificate proves you own the trademark; it’s a paid certificate from an approved CA.
What the tags mean
l=— the HTTPS URL of your SVG logo.a=— the HTTPS URL of your VMC PEM file. Omit it and some providers still show the logo; Gmail and Apple Mail won’t.
Where to publish it
Publish it as a TXT record at the host default._bimi (so the full name is default._bimi.yourdomain.com). default is the standard selector unless you have a reason to use another.
Frequently asked questions
What is a BIMI record?
BIMI (Brand Indicators for Message Identification) is a DNS TXT record that tells mailbox providers where to find your brand logo, so it can appear next to your messages in the inbox. It's published at default._bimi.yourdomain.com.
What are the requirements for BIMI to work?
Three things: a DMARC policy at enforcement (p=quarantine or p=reject with pct=100), a logo in SVG Tiny PS format hosted over HTTPS, and — for Gmail and Apple Mail — a Verified Mark Certificate (VMC) from an approved certificate authority.
Do I need a VMC?
For Gmail and Apple Mail, yes — they require a Verified Mark Certificate, which is a paid certificate that proves you own the trademark to your logo. Yahoo and Fastmail can display BIMI logos without one.
Why must the logo be an SVG?
BIMI requires the SVG Tiny Portable/Secure (SVG Tiny PS) profile specifically — a constrained, scripting-free SVG. Raster formats like PNG and JPG are not accepted.
