When a BIMI logo doesn't appear in Yahoo Mail after implementation, several factors can be at play. DMARC policy must be set to 'quarantine' or 'reject.' It's wise to allow a 72-hour waiting period for display. Sender reputation may need to be established. Verify the BIMI DNS record is correctly formatted and accessible. The SVG image must meet specific criteria, being publicly accessible via HTTPS, of a specific format and under 32KB. VMC certificates must be issued by accepted Certificate Authorities. Enroll in Yahoo's Complaint Feedback Loop (CFL) through the Sender Hub. Use tools like aboutmy.email for implementation checks. While a VMC isn't always required for Yahoo, it’s recommended. Also consider that logo display inconsistencies can occur across Yahoo domains and app versions, and reaching out to Yahoo Mail support may be necessary for specific issues. BIMI primarily serves as a brand indicator, and should not be thought of as a deliverability tool.

After implementing BIMI, the logo may not immediately appear in Yahoo Mail due to various reasons. These include: DMARC policy settings, which should be set to 'quarantine' or 'reject'; potential delays in logo display requiring a waiting period; sender reputation not meeting Yahoo's threshold; incomplete implementation steps, necessitating a checklist review; inconsistencies in logo display across Yahoo domains or app versions; failure to enroll in Yahoo's Complaint Feedback Loop (CFL) or sender hub, or DNS records or SVG requirements are not right; and the possibility of needing direct support from Yahoo Mail to resolve specific account issues. A VMC is recommended but may not be required for Yahoo.

When BIMI logos fail to appear in Yahoo Mail post-implementation, experts recommend a multi-faceted approach to troubleshooting. This includes verifying BIMI implementation and reputation using tools like aboutmy.email. Crucially, enrollment in Yahoo's Complaint Feedback Loop (CFL) via the Sender Hub is highlighted as a potentially effective solution for improving logo visibility upon approval. Ensuring the SVG file is properly formatted and served over HTTPS is also critical. Additionally, it's important to remember that BIMI primarily serves as a brand indicator, not a deliverability tool, so its implementation shouldn't be expected to directly impact deliverability rates.

According to official documentation, the failure of a BIMI logo to display in Yahoo Mail after implementation is often tied to specific technical requirements. The DMARC policy must be set to 'quarantine' or 'reject'; a 'none' policy will prevent the logo from appearing. Errors in the BIMI DNS record can also hinder display, necessitating careful verification of its format and accessibility. Furthermore, the SVG image must conform to particular format standards, be publicly accessible via HTTPS, and remain under 32KB in size. Finally, if using a VMC, it must be issued by an accepted Certificate Authority.
