## The guide in text

Greenline Pest Control (made up) gets the same questions every day. 5 steps to a reply waiting under each one.

## Step by step

1. ### Watch the inbox with a Gmail Trigger
   Pick the business inbox, then Fetch Test Event to see Dana's email as data: From, Subject, snippet and threadId.
2. ### Feed each email to an AI Agent
   Set Source for Prompt to Define below and pull in From, Subject and the message with expressions.
3. ### Give it a drafts-only tool
   A Gmail Tool with the resource set to **Draft**, and Thread ID set so the draft lands in the same conversation.
4. ### Write the rules
   Who it is, what it knows, the rules (drafts only, never make up prices, dates or services) and how to write.
5. ### Read the draft, then publish
   Dana's draft says yes to Maple Grove, $149 for the first visit, and asks for her address. You send it.

Businesses and people in the examples are made up (Greenline Pest Control is a made-up business). The steps, screens and wording come from the free lesson and the Stepthrough glossary and prompt library.
