Summary

Yahoo's Feedback Loop (FBL) is a critical tool for email senders to monitor user complaints. When FBL reports are missing or delayed, it can indicate underlying issues affecting email deliverability. Recently, some senders have reported a lack of FBL data, prompting concerns about the system's reliability. It's essential to understand the typical functioning of the FBL and what steps to take if you suspect a problem with your reports.

What email marketers say

Email marketers often rely heavily on Feedback Loop (FBL) data to gauge subscriber engagement and manage their sender reputation. When Yahoo FBL reports are not received, it causes significant concern, as it removes a vital source of information for optimizing email campaigns and preventing blocklists. Marketers frequently discuss these anomalies, sharing observations across various sending platforms and strategies.

Email deliverability experts often have deeper insights into the technical workings of FBLs and the broader ecosystem of internet service providers (ISPs). Their perspectives are invaluable for understanding whether reported FBL issues are isolated incidents, system-wide problems, or indicators of broader changes in how ISPs manage complaint data. Given their direct or indirect communication with ISPs, their input can clarify the nature of these outages or changes.
