Please check back frequently for changes and updates. Future BIMI programs may require BIMI certificates. 
Note:

  • these steps and resources are not final and will be updated as new information becomes available.
  • Each participating mailbox provider has their own criteria for determining when a domain’s BIMI logo may be displayed. Please see the Senders FAQ for more guidance.

Step 1

Authenticate all of your organization’s emails with SPF, DKIM and DMARC – ensure all are aligned

  • DMARC policy must be at enforcement – either “p=quarantine” or “p=reject” on the organizational domain
  • No sp=none or pct<100

Step 2

Produce an SVG Tiny PS version of your official logo

Step 3

Publish a BIMI record for your domain in DNS

a= tag is currently optional

  • default._bimi.[domain] IN TXT “v=BIMI1; l=[SVG URL]; a=[PEM URL]
  • View your BIMI record BIMI Inspector
