How does list hygiene contribute to placement?

List hygiene directly improves placement:

Remove bad addresses: Bounces generate negative signals. Clean them immediately.

Suppress complainers: Users who mark you spam will do it again. Remove them.

Sunset disengaged: Users who never open drag down metrics. Suppress them.

Better metrics: Cleaner lists show higher engagement rates. Providers see a sender whose mail is wanted.

List hygiene is not about size reduction. It is about signal quality improvement.
