AI Email Draft Generator for Gmail (IMAP) in n8n

Automatically generate Gmail email drafts from new incoming messages using AI inside n8n

This n8n automation workflow detects new emails via IMAP, uses a custom AI model to draft a relevant response, and saves the result directly as a Gmail draft—so you can review and send faster without manually writing from scratch.

What this workflow does

• Detects new emails 24/7 using the Check New Email (IMAP) node, capturing incoming message content for processing.
• Analyzes and drafts responses with AI by passing the email content into a language model (e.g., Llama) to generate structured, relevant email content.
• Prepares the response for Gmail so the output is ready for human review rather than sending immediately.
• Saves the generated response as a Gmail draft, enabling a review-and-send workflow with reduced delays.

Use cases

• Sales follow-ups: turn new inbound messages into polished draft responses while you stay focused on strategy.
• Operations and SaaS communications: generate consistent drafts for recurring questions, updates, or requests.
