Submitting multiple Yahoo Feedback Loop (FBL) requests is not supported through a consolidated bulk method. The process is predominantly a one-at-a-time, per-IP application directly with Yahoo, which now manages its own FBL program. Email marketers have reported encountering what seems to be daily submission limits, with some experiencing issues after approximately 15-16 submissions, suggesting system instability. While a workaround involving multiple browsers has been suggested for managing numerous individual submissions, senders should anticipate a manual process for each distinct IP address or IP range they wish to register.
9 marketer opinions
Registering multiple IP addresses for the Yahoo Feedback Loop (FBL) requires an individual approach for each, as a consolidated bulk submission method is not currently offered. Unlike past practices, Yahoo now directly oversees its FBL program, making it essential to apply separately for every unique IP address or range you use for sending. Email marketers have noted that verification emails might stop after a certain number of submissions, indicating potential daily limits or system constraints, which can complicate efforts to enroll a large number of IPs. While a tedious process, the current model necessitates completing each FBL request one by one.
