As of March 2021 Verizon Media is using BIMI and Gmail has entered a US based beta trial.
Verizon Media (Verizon, Yahoo & AOL) have publicly stated they have discovered an average 10% increase in open rates for email messages with brand logos on them.
BIMI is still in development so standards may change. Up to date information can be found here: https://bimigroup.org/all-about-bimi/
How can I implement BMI?
First, authenticate all of your emails with SPF, DKIM and DMARC.
- Ensure for domain alignment.
- Ensure your DMARC policy is enforced for both organisational domain and subdomains - this means either p=quarantine or p=reject.
- Publish a BIMI record for your domain in DNS.
A BIMI record generator can be found here: https://bimigroup.org/bimi-generator/
Verified mark certificate (VMC)
Gmail requires the VMC for their participation in their beta. Gmail’s beta is currently not accepting new senders.
Verizon has publicly stated:
‘We honor BIMI records on sub-domains, but prefer BIMI and DMARC to be set up at the organizational domain level.
We currently do not require VMCs to be set up for BIMI logos to appear in Verizon Media applications. However if a BIMI record includes a VMC, we might use it to inform the overall BIMI eligibility.’
The logo must be square, and saved as a version of the Scaled Vector Graphic (SVG) format.
Specifically, the SVG logo must follow the restrictions defined by the SVG Tiny 1.2 profile published by the W3C in 2008.
The logo cannot include any <script> tags and should not include any external links.
