AI Sales Agent in n8n: Write the follow-up email When a call recording is ready

An n8n workflow that fires when a call recording is ready, then an AI agent drafts a tailored follow-up referencing the last touch — giving you a follow-up ready before the call ends. No code: import the JSON, connect your apps, and it runs 24/7.

  1. 1

    Trigger when a call recording is ready

    A Google Drive Trigger starts the workflow the moment a call recording is ready.

  2. 2

    Hand it to the AI agent

    An AI Agent node running Claude drafts a tailored follow-up referencing the last touch. The prompt is pre-written and scoped to this one job so results stay consistent.

  3. 3

    Deliver the follow-up

    The result is sent to HubSpot — ready for a human to approve.

  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 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 follow-up 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.

Does this need n8n Cloud or can I self-host?

Either works. The workflow is a standard n8n export, so you can run it on n8n Cloud or on your own self-hosted instance — you only connect your own app credentials.
