Summary
The responses overwhelmingly indicate that there isn't a comprehensive, publicly available list of domains participating in the Yahoo Feedback Loop (FBL). Experts and documentation alike confirm that Yahoo doesn't publish such a list. The most consistent recommendation is to actively monitor your FBL reports and manage your email lists accordingly. It's also crucial to consider the impact of DKIM-based FBLs, which can generate complaints from domains outside the Yahoo ecosystem. Utilizing MX records to identify domains using Yahoo infrastructure can be helpful as a starting point, but remember, it's not exhaustive. Focusing on general email deliverability best practices and maintaining clean email lists are critical for mitigating deliverability issues. While Spam Resource offers a list of Yahoo and AOL domains, it's important to remember that this list may not be 100% accurate.
Key findings
- No Official List Exists: Yahoo does not provide a public, complete list of domains participating in their Feedback Loop.
- FBL Monitoring is Essential: The most reliable method is to actively monitor your Feedback Loop reports and adjust your lists based on complaint data.
- DKIM-Based FBLs: Complaints can originate from domains that aren't directly Yahoo-related due to forwarding and DKIM-based FBL mechanisms.
- MX Records as a Starting Point: Identifying domains using Yahoo's email infrastructure (via MX records) can provide a helpful starting point for identification but shouldn't be considered comprehensive.
- Third-Party Lists are Incomplete: While resources like Spam Resource maintain lists of Yahoo/AOL domains, these lists are not guaranteed to be exhaustive.
Key considerations
- Implement Regular FBL Monitoring: Establish a process to regularly monitor your Feedback Loop reports to identify and remove complainers promptly.
- Focus on Best Practices: Prioritize overall email deliverability best practices, including list hygiene, authentication, and engagement, to improve sender reputation.
- Acknowledge DKIM-Related Complexity: Be aware that DKIM-based FBLs can generate complaints even when the recipient isn't directly using a Yahoo or AOL address, making it difficult to rely solely on domain lists.
- B2B Considerations: If your audience is primarily B2B, the impact of the Yahoo FBL might be less significant, but maintaining clean lists is still essential.
- Signup for FBL Programs: Sign up with Return Path for Yahoo’s FBL and SNDS/JMRP for Microsoft to improve deliverability
