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
- Scalable Vector Graphics (SVG) Tiny PS Specification

Step 3
Publish a BIMI record for your domain in DNS
a= tag is currently optional
