AI-Assisted Lead Follow-Up With Human Approval

This workflow automates your lead response process from end to end. When someone submits your n8n Form, the workflow generates an AI-written follow-up email, sends that draft to your sales team for approval, and then sends the approved email to the lead or marks it as needing revision. All lead details, drafts, approval decisions, and timestamps are stored in Airtable.

Ideal For

  • Teams that want AI to draft emails while keeping a human approval step

  • Businesses receiving inbound inquiries that need fast, consistent responses

  • Users building a simple form → email → CRM workflow

  • Teams that want a record of all drafts and approval outcomes

What This Template Provides

  • AI-generated follow-up email drafts

  • Human approval flow, using Approve and Reject links
