AI Email Auto-Responder Setup

I want to bring an AI-driven auto-responder into my email workflow so incoming messages receive clear, factual answers without my manual input. The scope is focused on one channel—Email—yet the architecture should be clean enough that I can extend it later to SMS or Social Media if the business grows.

The responder must:
• Read and understand new emails in real time (IMAP/SMTP, Google Workspace).
• Generate concise, fully automated informational replies in English only, drawing on a small knowledge base or set of answer templates I will supply.
• Fall back to a default template or flag messages whenever the model’s confidence dips below an agreed threshold.
• Log every interaction for easy review and fine-tuning.

Tech I’m already comfortable with includes Python, FastAPI, and the OpenAI API, so please stay in that ecosystem unless you have a strong reason to suggest otherwise. A lightweight admin panel where I can update answer snippets, adjust the confidence threshold, and enable/disable the bot is essential.

Deliverables
1. Source code (well-commented) and a brief README showing setup commands.
2. A hosted demo or Docker container proving the responder works end-to-end with a test mailbox.
3. Documentation covering how to retrain or extend the model and how to add channels or languages later.
4. One test session where we validate responses against a checklist of sample emails I will provide.

I’ll handle domain-specific content and final template wording; you handle the AI logic, email integration, and deployment. Let me know your timeline and any clarifying questions so we can kick this off quickly.
