Summary
Updating a BIMI logo on Yahoo Mail requires a multi-faceted approach. First, allow a few days for Yahoo's cache to refresh. Verify the BIMI record is correctly configured, meets Yahoo's logo specifications (size, format, accessibility), and the DNS propagation is complete. Ensure the domain in the BIMI record matches the sending domain. A valid VMC (Verified Mark Certificate) issued by an authorized authority is crucial. A strict DMARC policy (p=quarantine or p=reject) is mandatory. Troubleshoot by clearing browser cache, re-uploading the logo with a new filename, validating the BIMI record's syntax, adjusting DNS TTL, and confirming the record is on the correct subdomain. If issues persist, contact Yahoo support and monitor your domain's reputation and sender score.
Key findings
- Yahoo Caching: Yahoo caches images; allow a few days for updates to appear, then consider contacting support.
- BIMI Record and Logo Specs: Ensure the BIMI record is correctly configured, published on the correct subdomain, and that the logo meets Yahoo's specifications.

- Troubleshooting Steps: Clear browser cache, try re-uploading the logo with a new filename, and use a BIMI validator tool.
- DNS TTL Adjustment: Consider lowering the DNS TTL for faster propagation.
- Contact Yahoo Support: If issues persist, contact Yahoo support for further assistance.
