📧 Master Your First AI Email Agent with Smart Fallback!

Welcome to your hands-on guide for building a resilient, intelligent email support system in n8n! This workflow is specifically designed as an educational tool to help you understand advanced AI automation concepts in a practical, easy-to-follow way.

🚀 What You'll Learn & Build:

This powerful template enables you to create an automated email support agent that:

• Monitors Gmail for new customer inquiries in real-time.
• Processes requests using a primary AI model (Google Gemini) for efficiency.
• Intelligently falls back to a secondary AI model (OpenAI GPT) if the primary model fails or for more complex queries, ensuring robust reliability.
• Generates personalized and helpful replies automatically.
• Logs every interaction meticulously to a Google Sheet for easy tracking and analysis.

💡 Why a Fallback Model is Game-Changing (and Why You Should Learn It):

• Unmatched Reliability (99.9% Uptime): If one AI service experiences an outage or rate limits, your automation seamlessly switches to another, ensuring no customer email goes unanswered.
• Cost Optimization: Leverage more affordable models (like Gemini) for standard queries, reserving premium models (like GPT) only when truly needed, significantly reducing your API costs.
• Superior Quality Assurance: Get the best of both worlds – the speed of cost-effective models combined with the accuracy of more powerful ones for complex scenarios.
• Real-World Application: This isn't just theory; it's a critical pattern for building resilient, production-ready AI systems.

🎓 Perfect for Beginners & Aspiring Automators:

• Simple Setup: With drag-and-drop design and pre-built integrations, you can get this workflow running with minimal configuration. Just add your API keys!
• Clear Educational Value: Learn core concepts like AI model orchestration strategies, customer service automation best practices, and multi-model AI implementation patterns.
• Immediate Results: See your AI agent in action, responding to emails and logging data within minutes of setup.

🛠️ Getting Started Checklist:

To use this workflow, you'll need:

• A Gmail account with API access enabled.
• A Google Sheets document created for logging.
• A Gemini API key (your primary AI model).
• An OpenAI API key (your fallback AI model).
• An n8n instance (cloud or desktop).
