AI Support Email Automation

I’m looking to set up a straightforward AI-driven workflow that automatically crafts and sends accurate, friendly replies to two types of incoming messages: general questions and support inquiries.

Here’s what I need:
• A lightweight solution that plugs into our existing email account (Gmail/Outlook or a simple IMAP connection is fine).
• An AI model—ChatGPT, GPT-4, or a comparable service—that you’ll configure with a short set of rules and example answers so it can recognise the difference between general queries and true support tickets, then draft an appropriate response for each.
• Basic fallback logic: if the message is unclear or the AI’s confidence is low, flag it for human review instead of sending.
• Clear instructions or a short Loom video showing me how to retrain or adjust the prompt set in the future.

I don’t need a full contact-center suite—just a reliable, neatly documented starter setup that I can expand later. If you have previous examples of similar email-response automations, that will help me choose quickly.
