Build your first email agent with fall back model

## 💡 Why Use a Fallback Model?

### Reliability
- **99.9% uptime** - If one model fails, the other continues
- **No missed emails** - Every customer gets a response

### Cost Optimization
- **Use cheaper models first** (Gemini) for simple queries
- **Reserve premium models** (GPT-4) for complex cases
- **Reduce API costs** by 60-80%

### Quality Assurance
- **Best of both worlds** - Speed + accuracy
- **Consistent responses** even during API outages
- **Improved customer satisfaction**
