How to implement BIMI on a subdomain without affecting the main domain or transactional emails?

Implementing BIMI on a subdomain without affecting the main domain or transactional emails requires careful configuration. The core strategy involves creating and deploying a distinct BIMI record specifically for the subdomain in the DNS settings, ensuring the BIMI logo only appears on emails sent from that subdomain. If a VMC is used, it should be valid for both the organizational domain and the subdomain. Additionally, the subdomain's DMARC policy needs to be properly aligned to maintain deliverability. For transactional emails, options include setting up a separate subdomain or using a profile picture for the sending address, recognizing that BIMI application is typically domain-wide. Given that BIMI doesn't inherently allow specifying particular email addresses, DNS record management and considering DMARC alignment are crucial.

Implementing BIMI on a subdomain requires careful configuration to avoid impacting the main domain or transactional emails. The key is to create and deploy a separate BIMI record specifically for the subdomain in DNS settings. The VMC, if used, should be valid for both the organizational domain and the subdomain. Ensure DMARC alignment for the subdomain to maintain deliverability. For transactional emails, options include setting up a separate subdomain or using a profile picture for those addresses, as BIMI cannot be selectively removed while still functioning.

Implementing BIMI on a subdomain without affecting the main domain or transactional emails requires specific configuration steps. Key actions include creating and deploying a BIMI record specifically for the subdomain. Given BIMI's domain-wide application, controlling which emails display the logo involves configuring DNS records and considering how transactional emails are handled. Options for transactional emails include moving the BIMI record to the relevant subdomain, establishing a new subdomain, or using a profile picture for those addresses. Ensuring the subdomain has its own valid DMARC policy is also critical for the BIMI implementation to function correctly and avoid negatively affecting the overall email authentication posture.

Implementing BIMI on a subdomain while preserving the integrity of the main domain involves strategic DNS record management. The BIMI record should be placed specifically on the subdomain to limit the scope of the BIMI application. Utilizing a VMC necessitates that the certificate is valid for both the organizational domain and the subdomain, addressing validation requirements. Accurate configuration of DNS records for the subdomain, including the location of the logo and VMC (if applicable), is essential for a successful implementation.
