BIMI — Brand Indicators for Message Identification

Category: Before Enabling Filtering Services | Protocol: DNS / Email / Image

BIMI (Brand Indicators for Message Identification) allows your organization’s logo to be displayed directly in recipients’ inboxes next to the sender’s name. It serves both as a trust indicator and a visual identity tool for your communications.

I — What Does BIMI Provide?

• Visual Identification: Your logo is displayed in compatible email clients (Gmail, Apple Mail, Yahoo, etc.)
• Trust: Proves that the email is authenticated and genuinely comes from your organization
• Deliverability: Reduces the risk of being treated as spam for senders with a good reputation
• Protection: Strengthens security against spoofing

⚠️ Some email clients do not yet support BIMI. The feature is displayed only in compatible clients.

II — Prerequisites

BIMI strictly requires:

• SPF configured and compliant
• DKIM configured and enabled
• DMARC policy set to quarantine or reject (not none)
• Control over your domain’s DNS zone
• An SVG Tiny P/S logo hosted over HTTPS

III — BIMI Compliance Indicator

Your administration console displays the BIMI status in real time from the homepage, in the DNS indicators section.

IV — Create the BIMI SVG File

The BIMI protocol requires a very specific SVG format: SVG Tiny P/S.

Mandatory checks for your SVG file:

• Attributes: version="1.2" and baseProfile="tiny-ps"
• Remove dimension attributes (width, height, x, y)
• Add a non-empty <title> tag
• No external or embedded CSS styles
• Logo centered inside a square (square viewBox recommended)

The SVG must be hosted on a server accessible via HTTPS.

V — Create the BIMI DNS Record

💡 For maximum recognition (especially on Gmail), you can obtain a VMC (Verified Mark Certificate) from a certification authority. This certificate officially validates your BIMI logo.
