BIMI (Brand Indicators for Message Identification) lets domain owners publish a brand logo location in DNS so participating mailbox providers can show the logo next to authenticated email. It builds on DMARC enforcement; each provider decides whether, where, and how the logo appears.

What are the prerequisites for BIMI?

BIMI requires: 1) DMARC policy set to quarantine or reject (p=quarantine or p=reject), 2) A publicly hosted HTTPS BIMI logo URL pointing to an SVG Tiny P/S file, 3) For Gmail display: a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC).

What format does my BIMI logo need to be?

Your BIMI logo URL must point to an SVG Tiny P/S (Portable/Secure) file over HTTPS. The logo should be square and must not include scripts, animation, or external links. Use the SVG Tiny P/S converter if your file needs cleanup.

How long does BIMI take to appear in inboxes?

DNS changes can take up to 48 hours. Mailbox providers may also cache or recheck the logo later. BIMI display is not guaranteed; DMARC enforcement, logo validation, certificate status, and provider policy all matter.

Create the default._bimi DNS TXT value

Create a BIMI TXT record for default._bimi with v=BIMI1, your HTTPS BIMI logo URL in l=, and optional a= for a certificate URL. Mailbox providers decide whether to show the logo; Gmail requires a VMC or CMC.

No signup. Live syntax preview.

BIMI Configuration

Check your Logo File

Checks the local SVG in your browser for basic SVG Tiny P/S hints. Confirm baseProfile=tiny-ps. If the file fails, try the SVG Tiny P/S converter.

Logo URL (l) - Required

Use the public HTTPS BIMI logo URL for the SVG Tiny P/S file you host. View requirements

VMC/CMC Certificate URL (a) - Optional

Gmail requires a VMC or CMC before it displays the logo. Use the HTTPS PEM certificate URL if you have one. Learn about VMCs

Selector (Advanced)

The default selector is "default", which publishes at default._bimi. Change it only if you use multiple BIMI records.

What BIMI does

Logo recognition

A familiar logo can help recipients recognize your mail before they open it.

DMARC enforcement

BIMI depends on strict DMARC, which also helps protect your domain from spoofing.

BIMI certificates

For Gmail display, you need a Verified Mark Certificate (VMC) if you own a registered trademark, or a Common Mark Certificate (CMC) for qualifying marks without a registered trademark. The certificate links your logo to your domain.
