How to publish a BIMI record?

BIMI email specification gives a brand the agility to determine what logo should appear as the sender for outgoing emails. Its unique approach allows the brand to create a wholesome user experience with more than just their products, but also their customer touchpoints. Instead of the generic logo that is displayed by default by your mailbox provider, BIMI helps brands provide a more professional look and feel to their business and marketing emails. This can be useful if a brand wishes to keep the same main brand and/or use different logos for different contexts.

What are Key Requirements for BIMI?

Domain owners should note that they need to meet certain key requirements before configuring BIMI for their domains. They are as follows:

  • For BIMI to function, DMARC enforcement is a mandatory requirement. Make sure that you configure a DMARC analyzer for your domain and shift to a policy of p=reject/quarantine  
  • The next step is to have your BIMI complaint brand logo in place. According to BIMI logo, the correct SVG file format is SVG Tiny 1.2
  • The display of your BIMI logo is ultimately in the hands of your mailbox provider, so make sure BIMI is supported by your participating mailbox providers
  • Finally, implement BIMI for your domain by publishing your BIMI DNS record

How to Create a BIMI DNS Record?

For creating and publishing your BIMI record, start by identifying your root domain. This is the domain that would appear as the sender of your emails. Considering your domain name is, the next step should be creating your BIMI selector. Similar in function to DKIM selectors, a BIMI selector is rendered by receiving servers to extract your BIMI record during a DNS lookup.

Note: It is not mandatory to define a selector name, as you can go with the default selector. However, if you operate several brands located on subdomains and want to render a different BIMI logo for each of them, then you need to manually configure a BIMI-selector header to make that possible.
