What Is a Feedback Loop?
When ISPs (aol, hotmail, yahoo, etc.) provide email service providers (like Benchmark) tracking information regarding specific user spam complaints, this is known as a feedback loop. Since Benchmark is technically the sender, we receive the complaint and note it as such in your account. We automatically remove the complaining subscriber from your email list to avoid further complications. Feedback loops are necessary communications between email senders and various ISPs.
