Definition
Yahoo's feedback loop notifies senders when their email is marked as spam by Yahoo Mail users. Unlike some ISPs that require registration, Yahoo provides FBL data through their Yahoo Postmaster Tools. The reports include the complained address and timestamp, enabling automatic suppression.
Setup Process
- Go to Yahoo Postmaster Tools at postmaster.yahoo.com
- Verify your sending domain by adding a DNS record
- Configure your Return-Path to route FBL reports to a processing address
- Automate parsing of incoming FBL reports
- Immediately suppress any email address that appears in a report
Why It Matters
Yahoo expects senders to honour FBL data. Failure to suppress known complainers results in reputation damage and increased spam filtering. Yahoo's spam complaint threshold is stricter than most ISPs — keep rates well below 0.1%.
