BIMI Settings ​

Once enabled, the BIMI settings page will show you options available for BIMI configuration. This page is disabled by default.

Users can use the Settings tab to upload their BIMI-related information:

SettingDescription
BIMI Logo (File Type: svg)Upload the logo associated with your domain.
Note: The logo must conform with the BIMI logo specifications.
BIMI Verified Mark Certificate (pem)Upload your Verified Mark Certificate. These certificates must be purchased from a Certificate Authority.

Logo Requirements ​

The BIMI logo must comply with the following requirements and restrictions.

Required Specifications ​

Your BIMI logo file must have:

  • Square aspect ratio: 1:1 where viewBox width and height match
  • Centered logo: To accommodate displays with rounded corners or circles
  • Solid background color: Transparent backgrounds may not display as expected
  • File size: Smaller than 32 kilobytes
  • File format: Scaled Vector Graphics (SVG), specifically SVG Portable/Secure (SVG P/S)

SVG Structure Requirements ​

The SVG file must contain the following elements:

  • Valid SVG structure
  • Proper XML version and encoding declaration
  • baseProfile attribute set to "tiny-ps"
  • version attribute set to "1.2"
  • <title> element specifying the organization's name
  • <desc> element for accessibility (optional but recommended)
  • Unix format newlines

Your BIMI logo file must NOT contain:

  • External links or references (except specified XML namespaces)
  • Scripts, animations, or interactive elements
  • <style> tags or inline CSS
  • width and height attributes
  • x= or y= attributes within the <svg> root element

NOTE

In most cases, you can export to SVG Tiny 1.2, but the file will still require modifications to be fully BIMI-compliant. For more information, read the BIMI logo specifications.

Example XML Structure ​

Mailbox Support ​

Although the adoption of BIMI is increasing, there are still large Email Service Providers (ESPs) only testing or planning to implement BIMI. We can see a list of ESPs and their current support for BIMI at this Knowledge Base article BIMI Support by Mailbox Provider - BIMI Group.

Authority & Certificate ​

In order to obtain a certificate you'll need to purchase one from a certificate provider. A provider like DigiCert will follow the following process:

  • Prove domain ownership with DNS TXT record
  • Provide correctly formatted SVG Logo (Tiny P/S) for Validation
  • Verify Company Details
  • Verify the Company and Technical representative's identity
  • Check Domain Risk
  • Receive Certificate in Privacy-Enhanced Mail (PEM) standard
    • Common Mark Certificate (CMC): To qualify for a CMC, you need to prove prior use of the logo over a period greater than 1 year, and the logo must not be legally protected or trademarked.
    • Verified Mark Certificate (VMC): To qualify for a VMC, your logo must be legally trademarked and registered with the appropriate office for your region.

Once you received your relevant certificate you'll need to upload it onto DMARC Manager in Domain Management under BIMI Settings where the VMC or CMC (.pem file) is requested.
