Summary
Several potential factors contribute to the lack of feedback loop (FBL) messages in the Yahoo Sender Hub. These include: incomplete enrollment in the Yahoo Sender Hub FBL program; initial delays in receiving reports; not meeting Yahoo's complaint volume thresholds; incorrect ARF implementation; general deliverability problems; unverified domains; improper email authentication (SPF, DKIM, DMARC); low IP reputation; switchover issues between old and new FBL setups; deduplication problems with older FBL programs; incorrect DKIM selector configurations; and a possible probationary period for new IPs or domains. Manual intervention, contacting Yahoo support, and ensuring complete and correct setup and authentication are often necessary.
Key findings
- Enrollment Issues: Incomplete enrollment in the Yahoo Sender Hub FBL program prevents the reception of FBL messages.
- Delay in Reporting: There might be a delay in receiving initial FBL reports after setting up the feedback loop.
- Complaint Thresholds: FBL reports may only be generated if a certain spam complaint volume threshold is exceeded.
- ARF Implementation: Proper ARF implementation is crucial for receiving FBL messages.
- Deliverability: General email deliverability issues can cause delays or prevent FBL data.
- Authentication: Incorrect or incomplete email authentication drastically reduces deliverability and FBLs.
- Reputation: Low IP reputation or a sudden drop in sending reputation can impact FBL delivery.
- Switchover Problems: Switchover issues between old and new FBL setups can occur, requiring manual intervention.
- Deduplication: Deduplication issues with older FBL programs may prevent reports in the new system.
- DKIM Configuration: Incorrect DKIM selector configuration can lead to improperly routed FBL messages.
- Probationary Period: New IPs or domains may undergo a probationary period before FBL reports are activated.
Key considerations
- Verify Enrollment: Ensure all steps, including domain verification and enrollment, are fully completed.
- Allow Time: Wait a few days to a week after setup before expecting FBL reports to appear.
- Monitor Complaints: Ensure a sufficient volume and complaint rate to meet Yahoo's reporting threshold.
- Implement ARF: Verify and maintain correct implementation of the Abuse Reporting Format.
- Check Deliverability: Address general deliverability issues by following email best practices.
- Authenticate Email: Ensure proper email authentication (SPF, DKIM, DMARC).
- Monitor Reputation: Consistently monitor sending reputation and maintain good list hygiene.
- Contact Support: Contact Yahoo Sender Hub support for specific account issues.
- Manage Switchovers: Understand potential switchover issues between old and new FBL setups.
- Check DKIM Selector: Ensure the correct DKIM selector is configured within the Yahoo Sender Hub.
- Consider New Setups: Account for a possible probationary period for new sending setups.

What the experts say
4 expert opinions
Several potential reasons for not receiving feedback loop (FBL) messages in Yahoo Sender Hub have been identified. These include a lack of complaints being generated, a delay in FBL activation after setup, insufficient sender reputation, Yahoo not duplicating FBLs during switchover to the new Sender Hub requiring manual intervention, a probationary period for new IPs or domains, and not meeting Yahoo's minimum spam complaint threshold to trigger FBL reports.
Key opinions
- Low Complaints: No or very few complaints being generated can prevent FBLs.
- Delay in Activation: There may be a delay before FBLs start appearing after initial setup.
- Reputation Issues: Insufficient sender reputation can prevent FBL generation.
- Switchover Complications: Yahoo might not automatically duplicate FBLs during switchovers, requiring manual processes.
- New Setup Probation: New IPs or domains may undergo a probationary period before FBLs are activated.
- Complaint Thresholds: Yahoo might have a minimum complaint volume threshold before sending FBL reports.
Key considerations
- Check Complaint Volume: Ensure a reasonable volume and rate of emails being sent to generate complaints, if applicable.
- Be Patient: Allow sufficient time for FBL activation after setup, accounting for potential delays.
- Improve Reputation: Work to improve or maintain a good sending reputation.
- Investigate Switchover: If transitioning to the new Sender Hub, understand that manual intervention may be necessary to fully migrate FBLs.
- Account for Probation: Expect a possible probationary period for new sending setups.

Expert from Spamresource explains that if you've recently transitioned to a new IP or domain, it might take some time for Yahoo's systems to recognize the new setup and begin sending FBL reports. New setups often have a 'probationary' period.

According to documentation, not receiving feedback loop messages in Yahoo Sender Hub can be attributed to several factors. These include incomplete enrollment in the program, which necessitates completing all verification and enrollment steps. There might also be an initial delay in receiving reports, requiring a waiting period of a few days to a week. Additionally, feedback loop reports might only be generated when a specific complaint volume threshold is reached. Finally, correct implementation of the Abuse Reporting Format (ARF) is crucial for compliance with various providers, including Yahoo.
