What is BIMI?
BIMI (Brand Indicators for Message Identification) is an email standard that allows organizations to display their brand logo alongside authenticated emails in supporting email clients like Gmail, Apple Mail, and Yahoo Mail.
When a recipient sees your logo next to your email, it builds instant trust and recognition. BIMI works by publishing a DNS TXT record at default._bimi.yourdomain.com that points to your SVG logo and optionally a Verified Mark Certificate (VMC).
BIMI requires a valid DMARC policy at enforcement level (p=quarantine or p=reject), making it the capstone of a complete email authentication setup.
What is a Verified Mark Certificate (VMC)?
What VMC Does
A VMC is a digital certificate that proves you legally own the logo displayed via BIMI. It's issued by certificate authorities like DigiCert or Entrust after verifying your trademark registration.
Why VMC Matters
Gmail requires a VMC to display BIMI logos. Without it, your logo may appear in Apple Mail and Yahoo Mail but not in Gmail — the world's most popular email client with over 1.8 billion users.
BIMI Logo Requirements
SVG Tiny PS Format
Your logo must be in SVG Tiny Portable/Secure (SVG Tiny PS) format — a restricted SVG profile that prevents embedded scripts or external references.
Square Aspect Ratio
The logo should be perfectly square with a centered design. Email clients will display it in a circular crop, so keep important elements away from edges.
HTTPS Hosting
The logo must be served over HTTPS from a publicly accessible URL. The server must allow cross-origin access for email clients to fetch the logo.
DMARC at Enforcement
Your domain must have a DMARC policy of quarantine or reject. BIMI will not work with p=none.
BIMI needs DMARC enforcement
DMARC Report monitors your authentication and helps you reach p=reject — the DMARC policy level required for BIMI logo display.

"Best security tool for your own domains"
The weekly reports help me a lot to analyze quickly the emails sent from my domains and that gives me peace of mind.

"Control Centre for Email Security"
I like that we can see and check all reports on just 1 platform. We manage multiple domains, and monitoring them all in one place is essential.

"A great solution to a common email problem."
I have been using them for the last month after my Google business email started giving DMARC errors. I didn't even know what it meant at that time. After a little googling I found that people can spoof it as well. So far so good — the best thing is it protects every email.
