What Is BIMI?

Brand Indicators for Message Identification (BIMI) is an emerging email standard that lets you display your brand logo next to your emails in supported inboxes. When a recipient opens your email in Gmail, Apple Mail, Yahoo, or other supporting clients, they see your verified logo in the sender avatar area. BIMI is both a security signal and a branding opportunity — it provides visual confirmation that the email is authenticated and genuinely from your organization. Domains with BIMI see higher open rates, stronger brand recognition, and increased recipient trust.

What Prerequisites Does BIMI Require?

BIMI has strict prerequisites. Your domain must have a DMARC policy at enforcement level — either p=quarantine or p=reject (p=none is not sufficient). Your logo must be in SVG Tiny P/S format (a restricted, secure SVG profile). For Gmail and some other providers, you also need a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC) issued by a recognized certificate authority (DigiCert or Entrust). The BIMI TXT record itself is published at default._bimi.yourdomain.com and contains your logo URL (l= tag) and optional certificate URL (a= tag).

What Our Checker Validates

Our BIMI Record Checker runs a complete validation pass. It looks up the TXT record at default._bimi.yourdomain.com, verifies the logo URL (l=) points to a valid HTTPS endpoint serving an SVG Tiny P/S file, checks the certificate URL (a=) if present, and confirms your DMARC policy is at enforcement level. Common issues flagged include: using a standard SVG instead of SVG Tiny P/S, hosting the logo on HTTP instead of HTTPS, DMARC policy still at p=none, missing or expired VMC certificate, and malformed DNS record syntax.

Getting Started with BIMI

The path to BIMI starts with email authentication fundamentals. First, deploy DMARC using our DMARC Generator and progress to enforcement (p=quarantine or p=reject). Then prepare your logo in SVG Tiny P/S format using our BIMI SVG Converter. Host the converted logo on a publicly accessible HTTPS URL. If you need a VMC or CMC, obtain one from DigiCert or Entrust (SimpleDMARC can assist through our BIMI Certificate service). Finally, use our BIMI Record Generator to create the DNS entry and validate everything end-to-end with this checker.

Frequently Asked Questions

What is BIMI?
BIMI (Brand Indicators for Message Identification) allows you to display your verified logo in email clients next to your messages.
Do I need a VMC for BIMI?
Yes, most major mailbox providers (like Gmail) require a Verified Mark Certificate (VMC) to display your BIMI logo. Gmail requires a VMC or CMC for logo display. Apple Mail displays BIMI logos without a certificate for domains with DMARC at reject. Yahoo supports BIMI without a certificate but prioritizes domains that have one.
How do I get BIMI?
You need to enforce DMARC (p=quarantine or p=reject), buy a VMC, and publish a BIMI DNS record.
What is SVG Tiny P/S?
SVG Tiny P/S (Portable/Secure) is a restricted subset of the SVG specification designed for safe rendering in email clients. It prohibits scripting, external references, and other potentially dangerous elements. Standard SVGs from design tools do not meet this requirement.
What is the difference between VMC and CMC?
A Verified Mark Certificate (VMC) requires your logo to be a registered trademark. A Common Mark Certificate (CMC) does not require trademark registration, making it accessible to more organizations. Both are accepted by supporting mailbox providers.
Why does my BIMI check fail if I have p=none?
BIMI requires DMARC enforcement. A p=none policy means you are only monitoring — not blocking unauthorized email. Mailbox providers will not display your logo until you enforce at quarantine or reject.
How long does it take for my logo to appear?
After publishing a valid BIMI record with all prerequisites met, it can take several days to weeks for mailbox providers to detect and start displaying your logo. Google caches BIMI results and processes them in batches.
