Should I set up CFLs with Yahoo if delivery has been good for years?

Summary

The overwhelming consensus among email marketers, experts, and documented best practices is that setting up Complaint Feedback Loops (CFLs) with Yahoo is highly recommended, even when current delivery rates are satisfactory. The primary rationale is that CFLs provide a proactive mechanism for monitoring and managing sender reputation by gathering data on user complaints. This enables senders to identify and address potential issues before they negatively impact deliverability. While one source suggested a possible short-term delay under specific conditions, the prevailing advice stresses the importance of CFLs as a preventative measure, an early warning system, and a long-term investment in email deliverability.

Key considerations

  • Data Analysis & Action: The effectiveness of CFLs depends on the capacity to analyze the data and take appropriate action based on the findings.
