Summary
The general consensus is that displaying a logo in Yahoo Mail without DMARC and BIMI records is not reliably possible anymore. While Yahoo may have had legacy logo display programs or databases, these are outdated, unreliable, and no longer officially supported. BIMI (Brand Indicators for Message Identification) is the current recommended standard and requires DMARC compliance, specifically a policy of 'quarantine' or 'reject' enforced on both the parent domain and any subdomains. Proper email authentication and maintaining a good sender reputation are also essential for BIMI to work effectively.
Key findings
- Legacy Logo Methods Obsolete: Yahoo's past methods of displaying logos, such as through a logo database or based on domain reputation, are no longer reliable or supported.
- BIMI is the Current Standard: BIMI (Brand Indicators for Message Identification) is the only reliable way to consistently display logos in Yahoo Mail.
- DMARC is a Prerequisite: DMARC (Domain-based Message Authentication, Reporting & Conformance) compliance is mandatory for BIMI implementation.
- DMARC Policy Enforcement Required: The DMARC record must have a policy of 'quarantine' or 'reject' for BIMI to be validated and effective; enforcement needs to be on parent domain and subdomains.
- SVG Logo Required: A properly formatted SVG (Scalable Vector Graphics) version of the logo is required for BIMI implementation.
- Good Sender Reputation Important: Maintaining a good sender reputation is important for overall email deliverability and for meeting BIMI's requirements.
Key considerations
- Implement BIMI: If you want your logo to display consistently in Yahoo Mail, prioritize implementing BIMI.
- Configure DMARC Properly: Ensure your DMARC record is correctly configured and enforced on all relevant domains and subdomains, with a policy of 'quarantine' or 'reject'.
- Prepare SVG Logo: Create a properly formatted SVG version of your logo that meets BIMI specifications.
- Monitor Sender Reputation: Actively monitor and maintain a good sender reputation by following email best practices.
- Consider VMC (Optional): Consider obtaining a Verified Mark Certificate (VMC) for enhanced brand validation, although it is not strictly required.
