How do ESPs enforce complaint-based suppression standards?
ESPs enforce complaint based suppression through automatic FBL processing, threshold alerts, and potentially sending restrictions. When complaint rates exceed acceptable limits, ESPs may pause or restrict sending until issues are addressed.
Most ESPs automatically process available FBL reports and suppress complainers. They may provide dashboards showing complaint rates and trends. Alerts notify when rates approach problematic thresholds.
Enforcement escalates with severity. Minor threshold violations trigger warnings. Sustained high complaints may suspend sending privileges. Severe violations can result in account termination. ESPs protect their shared infrastructure reputation by enforcing standards.
