Gmail Lead Triage & Routing with Groq + Notion CRM (n8n)

Automatically triage unread Gmail leads, route them in Notion, notify managers, and place a Twilio confirmation call

This n8n workflow monitors your Gmail inbox for unread messages every hour, uses Groq (via LangChain) to classify and route each email, updates your Notion CRM databases, sends an assignment email, and triggers a Twilio confirmation call via HTTP.

What this workflow does

• Hourly Gmail lead intake: Triggers every hour and pulls all unread Gmail messages.
• Groq-based importance classification: Uses Groq-hosted LLM prompts (via LangChain) to classify each email as important or not important based on sender, subject, and snippet.
• Notion CRM lookups: For important emails only, fetches member/manager records and existing company records from Notion.
• Company matching & manager selection: Uses Groq (via LangChain) to match the email to an existing company, or to assign a new company and choose an active manager from the manager list.
• Notion update + new company creation: If the status is assigned, creates a new company record in the Notion Companies database with the selected manager and extracted company details.
• Manager notification + confirmation call: Sends an assignment notification email to the selected manager via Gmail, then triggers a Twilio confirmation call using the Twilio Calls API over HTTP.

Use cases

• Inbound lead routing: Automatically send important inquiries to the correct sales or account manager.
• CRM hygiene: Match emails to existing companies or create new company entries in Notion.
• Faster response workflows: Notify managers immediately and confirm assignment via Twilio calls.
