Reply to support emails automatically with a backup AI model

The system drafts replies to customer emails using AI, and switches models automatically if one fails.

How the work actually flows

It branches. Exactly one path is taken; it retries when a step fails.

The problem it solves

Customer emails pile up in your inbox and answering each one takes time you would rather spend elsewhere. If you rely on a single AI tool to help draft replies, an outage or hiccup can leave you stuck.

Who it fits

Best for a small support team that wants AI-drafted replies without a single point of failure.

How it works

  1. A new customer email arrives in Gmail
  2. The system reads the message and drafts a reply using its primary AI model
  3. If that model fails or the question is complex, it automatically switches to a backup AI model
  4. The reply is sent, and the interaction is logged to a spreadsheet
What you get

Responses ready before you open your inbox

Customer emails get a drafted reply automatically, and if one AI model struggles, a backup model steps in so nothing gets missed.

What you get

A drafted or sent reply to each customer email, plus a spreadsheet log of every conversation.

What you need

A Gmail account, a Google Sheets account, and API access to two AI providers such as Google and OpenAI.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
