How do bounces interact with feedback loops?

Bounces and feedback loops work together:

Different signals:

Bounces: Technical delivery failure. FBL: Recipient complained (marked as spam).

Complementary protection:

Bounces: Remove invalid addresses. FBL: Remove unwilling recipients. Together: Clean list of both bad and unwanted.

Shared suppression list:

Both should feed same suppression system. Address should be suppressed regardless of signal source. Unified view of address status.

Priority considerations:

FBL complaint: Often more urgent for reputation. Hard bounce: Definitive invalidity. Both warrant suppression.

Analytics integration:

Track both metrics together. Correlate patterns. Comprehensive list health view.

Bounces and FBL are two sides of list quality. One measures deliverability; the other measures desirability.
