How do inactive recipients contribute to silent filtering?

Inactive recipients contribute to silent filtering through accumulated negative signals:

When recipients consistently ignore your messages over months, providers learn that your mail is not valued by that audience segment.

Providers begin preemptively routing your messages to spam for these recipients without generating bounce notifications. Your delivery logs show success, but messages disappear.

The pattern can spread beyond individual recipients. If providers detect that a large portion of your list ignores you, they may increase filtering for your entire sending identity.

No feedback mechanism alerts you to the problem. Unlike bounces or complaints, silent filtering is invisible in standard reporting.

Inactive recipients are like merchants who accept shipments but never open the boxes. Eventually, the harbor routes your cargo to storage that nobody checks, and you keep shipping without realizing the goods never reach anyone.
