Harden outbound against bounce rate spikes

Validation, monitoring, and auto-pause to protect sender reputation.

Steps

Baseline bounce rate. Measure current bounce rate across all campaigns.
Pre-send validation. No unvalidated email enters a sequence.
Bounce webhook. Instantly/Smartlead bounces flow back to invalidate contacts.
Auto-pause. Campaign pauses if bounce rate exceeds 3% in a 24-hour window.
Root cause trace. Bounce spikes traced to enrichment source and list age.

Bounce rate below 2% sustained. Zero domain blacklisting events.
