Email Support Agent w/ Gemini & GPT fallback using Gmail + Google Sheets

📧 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).
