BIMI Settings ​

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

Use the Settings tab to upload your BIMI-related information:

SettingDescription
Logo (File type: svg)Upload the logo associated with your domain.
Note: The logo must conform with the BIMI logo specifications.
Authority & Certificate (File type: 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 ​

To obtain a certificate, you'll need to purchase one from a certificate provider. A provider like DigiCert follows this 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 have received your certificate, upload it to DMARC Manager. Go to Domain Management > BIMI Settings and upload the VMC or CMC (.pem file).
