BIMI Logo Repository

This repository hosts the brand logo files used for BIMI (Brand Indicators for Message Identification) — an email authentication standard that displays your company logo in recipients’ inboxes next to authenticated emails.

What is BIMI?

BIMI is a DNS-based standard that allows organizations to publish a verified brand logo that email clients (Gmail, Apple Mail, Yahoo, etc.) display alongside emails that pass DMARC authentication. It helps recipients identify legitimate email from your organization and reduces the effectiveness of phishing and spoofing attacks.

Requirements for BIMI to work:

• A valid DMARC policy of p=quarantine or p=reject
• An SVG logo in SVG Tiny P/S format hosted at a stable HTTPS URL
• A DNS TXT record at default._bimi.<yourdomain> pointing to the logo

This Repository

Files in this repo are referenced by BIMI DNS records managed in Cloudflare. Do not rename, move, or delete files without first updating the corresponding DNS TXT record — breaking the URL will silently disable BIMI for that domain.

Updating a Logo

1. Replace the SVG file in the appropriate directory
2. The new logo must comply with SVG Tiny P/S format (no CSS classes, no external references, version="1.2" baseProfile="tiny")
3. Commit and push — GitHub Pages serves the file automatically
4. No DNS change is needed unless the file path changes
