This n8n template drafts customer-ready email replies using Google Gemini, enriched with HubSpot context (contact, deals, companies, tickets). Each draft is routed to Slack for one-click approval before it’s sent from Gmail—so you move fast without losing control.

Ideal for support and sales teams that want speedy, personalized responses while keeping humans in the loop.

How it works

Gmail Trigger watches for new inbound emails. Sender filter excludes internal domains (e.g., n8n.io) to avoid auto-replying to teammates. HubSpot contact lookup finds the sender and fetches associated deals/companies/tickets via association + batch read. CRM context is normalized into clean, LLM-friendly fields (no IDs or sensitive noise). Gemini (Google AI Studio) generates a concise, friendly reply using:

Sender name, subject, and message snippet Safe, relevant HubSpot context (e.g., top 1–2 deals or an open ticket) Style constraints (≤ \~150 words, single CTA, optional clarifying question) Slack approval posts the draft to a channel; if approved, n8n replies via Gmail in the original thread.
