Summary
In the absence of BIMI, Yahoo Mail employs various methods to display a sender's logo, including legacy systems, algorithmic guesses based on domain reputation and public information, scraping logos, and using cached or shared data. These methods are unreliable and often result in incorrect logo display due to outdated or inaccurate information. Yahoo also generates initials as avatars when no image is available. The core issue is Yahoo's attempt to associate a logo without the formal verification that BIMI provides. These associations are prone to error and outdated information can result in incorrect logos being shown.
Key findings
- BIMI Absence: Lack of BIMI configuration triggers Yahoo to use alternative methods.
- Legacy Systems: Legacy systems may display logos incorrectly.
- Algorithmic Guessing: Yahoo guesses logos based on domain reputation and public data, often inaccurately.
- Data Sources: Yahoo uses WHOIS records, social media, and website scraping.
- Caching & Sharing: Yahoo may pull from old cached data or shared databases.
- Inference: Yahoo makes inferences that can be incorrect, inferring details from different entities.
- Outdated Association: Yahoo and other providers will attempt to associate a logo with a sending domain based on available data, but without the formal verification of BIMI, these associations are prone to error and outdated information can result in incorrect logos being shown.
Key considerations
- Implement BIMI: Implement BIMI for accurate logo display, including obtaining a VMC.
- Check Yahoo Resources: Consult Yahoo's help pages and guidelines.
- Update Public Data: Ensure public domain and company information are current.
- Yahoo Support: Tweeting at `@yahoomail` might resolve specific issues.

These methods often result in inaccuracies due to outdated information, incorrect associations, generic logos, or scraping the wrong logo from the sender's website. Ultimately it is 'best guess' work by Yahoo.

According to various documentation sources, the absence of BIMI configuration in Yahoo Mail leads to the incorrect logo being displayed because Yahoo attempts to identify and display a logo using information available on the internet, within their systems, WHOIS records, social media, and other public sources. These methods are unreliable and can result in errors due to incomplete or outdated information.

- Public Sources: Yahoo falls back on WHOIS records, social media, and other public sources to identify and display logos.
- Inaccurate Guarantees: Yahoo does not guarantee the accuracy of the logo if BIMI is not set up.
- Verified Ownership: BIMI uses a VMC (Verified Mark Certificate) to validate logo ownership.
Key considerations
- BIMI Configuration: Configure BIMI to ensure the correct logo is displayed.
- VMC Acquisition: Obtain a Verified Mark Certificate (VMC) for BIMI implementation.
