+**⚠️ NOTICE: Bounce handling is optional and disabled by default.**
 
 This document describes how to configure AWS SES and SNS to handle email bounces automatically in the Mail List Manager.
 
+**Prerequisites:**
+- SES production access (not available in sandbox mode)
+- Valid HTTPS domain for webhook endpoint
+- Bounce handling must be enabled in configuration

+The system can optionally use AWS Simple Notification Service (SNS) to receive real-time bounce notifications from AWS Simple Email Service (SES). When bounce handling is enabled and an email bounces:
 
 1. SES sends a notification to an SNS topic

+First, enable bounce handling in your `.env` file:

+```
+
+Restart the API container after making this change:

 - AWS account with SES configured and verified
 - Your Mail List Manager deployed and accessible via HTTPS (required for SNS webhook)
 - Domain or subdomain for webhook (e.g., `https://lists.yourdomain.com`)

+### Bounce Handling (Optional)
+
+**Email bounce handling is optional and disabled by default.**
+
+**Two Configuration Options:**
+
+1. **SNS Webhooks** (Requires SES Production Access):
+   ```bash
+   # In .env file
+   ENABLE_SNS_WEBHOOKS=true
+   ENABLE_BOUNCE_HANDLING=true
+   ```
+   - Real-time bounce notifications via AWS SNS
+   - Automatic member deactivation for hard bounces
+   - Bounce history tracking and management
+   - Requires valid HTTPS domain and SES production access
+   - See `BOUNCE_HANDLING_SETUP.md` for complete setup
+
+2. **Email-Based Handling** (Default for SES Sandbox):
+   ```bash
+   # In .env file (or leave these commented out)
+   ENABLE_SNS_WEBHOOKS=false
+   ENABLE_BOUNCE_HANDLING=false
+   ```
+   - Manual bounce management via email notifications
+   - No automatic processing - requires manual member cleanup
+   - Works with SES sandbox accounts
+   - Bounce-related UI elements are hidden
+
+**When bounce handling is disabled:**
+- `/webhooks/sns` endpoint is not registered
+- Bounce history endpoints return empty results
+- Web UI hides bounce badges and bounce management buttons
+- No automatic member deactivation occurs
+
