Please check back frequently for changes and updates. Future BIMI programs may require BIMI certificates. Please note, these steps and resources are not final and will be updated as new information becomes available.

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

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]
