Summary

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.

Key findings

  • Per-IP Enrollment: The Yahoo Feedback Loop (FBL) enrollment process is primarily on a per-IP basis, meaning each unique IP address or IP block requires its own application.
  • No Bulk Submission: There is no streamlined or official bulk submission mechanism for submitting multiple Yahoo FBL requests simultaneously. Each request must be handled individually and manually.
  • Direct Yahoo Management: Yahoo now directly manages its FBL program, rather than through third-party services like Return Path, requiring direct interaction with Yahoo for enrollment.

Key considerations

  • Individual Application Required: Prepare to submit a separate application for each distinct IP address or IP range you wish to register with the Yahoo Feedback Loop. There is no consolidated bulk submission option available.
  • Potential Submission Limits: Be aware that some users have experienced what appears to be a daily limit, with verification emails stopping after a certain number of submissions (e.g., 15-16). Plan your submissions accordingly to avoid hitting these unseen thresholds.
  • System Instability: Users have reported issues with Yahoo FBL signups and authentication, suggesting potential system instability. Be prepared for a potentially non-linear or challenging application process.

What email marketers say

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.

Key opinions

  • Individual IP Basis: Yahoo's Feedback Loop (FBL) enrollment is exclusively on a per-IP address basis, necessitating a separate application for each distinct IP or IP range.
  • No Consolidated Method: There is no central system or bulk submission portal available for simultaneously enrolling multiple IP addresses in the Yahoo FBL program; each must be processed individually.
  • Direct ISP Process: Yahoo, similar to other Internet Service Providers (ISPs), manages its own FBL program directly, requiring senders to apply through their specific, independent process.

Key considerations

  • Prepare for Individual Submissions: Plan to submit a distinct application for every unique IP address or IP block you wish to enroll in the Yahoo FBL, as no consolidated form exists.
  • Mind Daily Limits: Be mindful that some senders have observed what appear to be daily submission caps, with reports of applications ceasing to process after a certain number, such as 15-16. Adjust your application pace accordingly.
  • Anticipate Manual Effort: Given the absence of bulk tools, expect the process of enrolling multiple IPs in Yahoo's FBL to be a manual, time-consuming endeavor requiring individual attention to each request.

What the experts say

2 expert opinions

Submitting multiple Yahoo Feedback Loop (FBL) requests is primarily a one-at-a-time process, as Yahoo's system is structured to handle individual applications for each unique sending IP address rather than bulk submissions. While no official method exists for mass enrollment, a suggested workaround involves utilizing multiple browsers to manage numerous individual submissions. Senders should also be aware of reports indicating potential system instability, including known issues with FBL signups and authentication.

Key opinions

  • Individual IP Focus: Yahoo's FBL system is designed for singular applications, requiring a separate request for each distinct IP address.
  • No Bulk Mechanism: There is no official or built-in functionality for submitting multiple FBL requests simultaneously; each must be processed individually.
  • Workaround Suggested: Experts propose using multiple browsers as a practical, albeit manual, method to facilitate a higher volume of individual FBL submissions.
  • System Instability: Reports highlight ongoing issues with Yahoo FBL signups and authentication, suggesting a degree of system unreliability.

Key considerations

  • Prepare for Manual Submissions: Anticipate a highly manual process where each FBL request for a unique IP address must be handled separately.
  • Consider Browser Workarounds: If managing numerous IPs, explore the suggested technique of using multiple browsers to expedite individual submissions, understanding it's not an official bulk solution.
  • Account for System Glitches: Be prepared to navigate potential challenges like signup failures or authentication problems due to reported system instability when submitting FBL requests.

Expert view

Expert from Email Geeks confirms the Yahoo feedback loop submission limit is one at a time. She suggests a workaround using multiple browsers for bulk submissions and indicates there are known issues with Yahoo FBL signups and potential authentication problems, implying system instability.

Expert view

Expert from Spam Resource explains that the Yahoo Feedback Loop (FBL) program requires separate applications for each individual sending IP address. There is no stated method for submitting multiple FBL requests in a single bulk submission; instead, each unique IP address or sending entity needs to go through its own individual registration process.

What the documentation says

3 technical articles

Accessing the Yahoo Feedback Loop (FBL) for multiple IP addresses requires individual requests for each, as official documentation and industry experts confirm no bulk submission feature. Yahoo's own help resources, along with insights from Valimail and Mailchimp's knowledge base, consistently emphasize a manual, per-IP application process. This means senders must submit separate applications for every distinct IP address or range they wish to register, underscoring the necessity of individual rather than consolidated enrollment.

Key findings

  • Individual IP Applications: Enrollment for the Yahoo Feedback Loop consistently requires separate applications for each distinct IP address or IP block, as confirmed by official documentation.
  • No Streamlined Bulk Tool: There is no official or streamlined mechanism provided by Yahoo for submitting multiple FBL requests in a consolidated or bulk manner.
  • Manual Submission Mandated: The Yahoo FBL registration process is explicitly manual, necessitating individual data submission for every IP address seeking enrollment.

Key considerations

  • Prepare for Individual Forms: Senders must be ready to complete a separate application form for each unique IP address or IP range they wish to enroll in the Yahoo Feedback Loop.
  • Allocate Significant Time: Registering multiple IP addresses for the Yahoo FBL will be a time-intensive and manual process, given the absence of a bulk submission option.
  • Confirm IP Details Individually: Each FBL request requires specific IP address details and sender contact information to be provided on an individual basis.

Technical article

Documentation from Yahoo Help explains that to register for the Yahoo Feedback Loop, senders must provide their server IP address, an email address to receive feedback, and other contact details through a specific application form. This process implies individual submission per IP address, rather than a bulk upload option for multiple requests.
