  1. 1

    Trigger when a new signup lands in your sheet

    A Google Sheets Trigger starts the workflow the moment a new signup lands in your sheet.

  2. 2

    Hand it to the AI agent

    An AI Agent node running OpenAI matches the lead to the right rep by territory and size. The prompt is pre-written and scoped to this one job so results stay consistent.

  3. 3

    Deliver the routing

    The result is sent to Gmail — instantly, no clicks needed.

  4. 4

    Add a safety net (optional)

    Insert an IF/human-approval step before anything is published or emailed, so you stay in control until you trust the output.

Frequently asked questions

How do I import the workflow into n8n?

Download the JSON, then in n8n open a new workflow, choose ⋯ → Import from file, and select it. Every trigger, node and connection appears on the canvas; you just add your credentials and activate it.

How much does the AI part cost to run?

Pennies. Each run sends a small amount of text to the model, so most teams spend a few dollars a month even at hundreds of runs. You set the model and can cap volume in n8n, so costs never surprise you.

Can I trust the AI to get the routing right?

The prompt is tightly scoped to one job and you can add a human-approval step in n8n before anything is sent or published. Start with review-mode for a week, and once you trust the output, switch it to fully automatic.
