Bounce Shield Protection
Bounce Shield is WarmySender's configurable bounce protection system:
Settings (from Settings > Bounce Shield):
- Enable/Disable — Toggle bounce protection on or off (default: ON)
- Bounce Threshold — Percentage threshold that triggers protection (default: 10%, range: 1-20%)
- Window Size — Number of recent emails evaluated for bounce rate calculation (default: 200, range: 50-1,000)
- Auto-Pause Campaigns — Automatically pause campaigns when threshold is exceeded (default: ON)
- Auto-Add to Blocklist — Automatically add bounced email addresses to your suppression list (default: ON)
- Email Notifications — Receive email alerts when Bounce Shield triggers (default: ON)
How It Works:
- WarmySender monitors bounce rates across your recent sends
- When the bounce rate within the configured window exceeds your threshold, Bounce Shield activates
- If auto-pause is enabled, affected campaigns are paused to prevent further damage
- If auto-blocklist is enabled, bounced addresses are added to your suppression list
- You receive an email notification (if enabled)
This is in addition to the per-campaign safety metrics (5% bounce rate threshold with 50 minimum sends). Bounce Shield provides workspace-level protection across all campaigns.
Best Practice: Keep the default settings. Lower the threshold to 5% if you are very cautious about deliverability. Verify your email lists before importing to reduce bounces.
