Summary

The absence of FBL (Feedback Loop) reports from specific ISPs, such as Telenor (including online.no) and potentially others serviced by Validity, has been a significant concern for email senders. These reports are crucial for monitoring complaint rates and maintaining sender reputation, making their disappearance a critical issue for deliverability. This section summarizes why you might not be receiving these vital reports.

What email marketers say

Email marketers often rely heavily on FBL reports to understand their audience's perception of their emails and to mitigate potential spam issues. The absence of these reports, especially from key ISPs or via major providers like Validity, can leave marketers feeling blind regarding their sender reputation. Discussions among marketers highlight shared frustrations and attempts to troubleshoot these reporting gaps.

Marketer view

Email marketer from Email Geeks observes that they haven't seen any FBL reports from online.no (Telenor) in the last 120 days, and doubts having received any in the past year or so, despite Telenor supposedly having an FBL operated by Validity. This raised concerns about the consistency of report delivery.

Expert from spamresource.com observes that when an FBL feed goes quiet, it's often a sign that either the volume of complaints has dropped significantly, or there's a technical issue on the FBL provider's side. Distinguishing between the two requires investigation.

What the documentation says

Technical documentation and industry standards provide the foundation for how Feedback Loops are designed and operated. Understanding these underlying principles can help diagnose issues when FBL reports are not received. Key documents often outline the expected format, delivery mechanisms (e.g., ARF), and general operational guidelines for FBLs.

Technical article

Documentation from RFC 5965, the Abuse Reporting Format (ARF), specifies that FBLs are designed to provide feedback on unsolicited bulk email (UBE). The absence of these reports might mean that your mail is not being perceived as UBE by the ISP's filtering systems, or that the reporting mechanism is failing.

Technical article

Validity's official UFL documentation explains that FBLs aggregate user spam complaints and send them to the responsible sender. If there are no reports, it could indicate low complaint volumes or a disruption in Validity's processing and forwarding of data for a specific ISP.
