Marketer from Email Geeks explains that BIMI requires the org domain to be at p=reject or p=quarantine.

Marketer from Email Geeks shares that you can get the BIMI certificate for just the org domain, and it will be inherited if you publish your BIMI record only at the org domain.
Marketer from Email Geeks mentions that using a shared IP can impact your logo's display because deliverability affects BIMI, even when technical requirements are met.
Email marketer from SparkPost warns that shared IPs can affect sender reputation. To overcome this, monitor IP reputation, implement feedback loops, and work to maintain high engagement rates.
Email marketer from Litmus states that BIMI is domain-based, not IP-based. So, a shared IP address doesn't prevent BIMI from working, as long as you have control over your domain's authentication (SPF, DKIM, DMARC) and a valid VMC.

What the documentation says4Technical articles
Documentation from DigiCert Knowledge Base emphasizes that BIMI requires a valid DMARC policy set to either 'quarantine' or 'reject.' It mentions that while a dedicated IP isn't strictly necessary, maintaining a good sender reputation is crucial on shared IPs to ensure logo display.
Documentation from Entrust Blog highlights the need for a Verified Mark Certificate (VMC) to display a logo through BIMI. It notes that you can obtain a VMC for your primary domain, even when sending from subdomains on a shared IP, provided your DMARC policy is correctly implemented.
Documentation from BIMI Group Website confirms that BIMI works independently of IP addresses, meaning it's compatible with shared IP environments as long as domain authentication standards (SPF, DKIM, DMARC) are properly configured.
Documentation from dmarcian recommends a phased approach to DMARC deployment, starting with 'p=none' to monitor traffic, then moving to 'p=quarantine' and eventually 'p=reject'. This helps minimize disruption and identify any authentication issues before enforcing a stricter policy.
