Webhook Retry Logic & Delivery Improvements

What's New

We've implemented a robust retry mechanism for webhook deliveries to ensure your applications receive email notifications even when experiencing temporary connectivity issues.

Key Improvements

🔄 Automatic Retry Logic

• Failed webhook deliveries are now automatically retried up to 3 times
• Exponential backoff between retries (1s, 4s, 16s)
• Prevents overwhelming your servers during recovery

📊 Enhanced Delivery Tracking

• New webhook delivery status tracking in the dashboard
• View retry attempts and failure reasons
• Real-time webhook health monitoring

⚡ Performance Optimizations

• Parallel webhook delivery for multiple endpoints
• Reduced latency for successful deliveries
• Better handling of timeout scenarios

Configuration Options

You can now configure webhook behavior per endpoint:

{
  "url": "https://your-app.com/webhook",
  "timeout": 30000,        // Custom timeout (ms)
  "retryAttempts": 3,      // Number of retry attempts
  "retryDelay": 1000       // Initial retry delay (ms)
}

Webhook Response Requirements

To ensure proper retry behavior, your webhook endpoint should:

• Return 2xx status codes for successful processing
• Return 5xx status codes for temporary failures (will retry)
• Return 4xx status codes for permanent failures (won't retry)

Monitoring

New metrics available in your dashboard:

• Webhook success rate
• Average delivery time
• Retry attempt distribution
• Failed delivery reasons

This update requires no changes to your existing webhook endpoints and is fully backward compatible.
