GPT-4o Lead Scoring n8n Webhook → Gmail & Google Sheets

Turn every lead enquiry into a scored decision—automatically

This GPT-4o Lead Scoring n8n Webhook → Gmail & Google Sheets workflow receives new enquiries via a webhook, enriches and scores them with OpenAI GPT-4o, then routes leads instantly: priority leads get emailed via Gmail, mid-fit leads are added to Google Sheets for nurture, and low-fit/out-of-scope leads receive a polite decline email.

What this workflow does

• Accepts a webhook request: listens for POST requests on /lead containing a new enquiry.
• Prepares lead context: attaches your ideal customer profile and urgency signals to the incoming data.
• Enriches lead details with GPT-4o: uses an OpenAI GPT-4o orchestrator agent to call an enrichment sub-workflow that extracts structured, knowable facts from the enquiry.
• Scores lead fit 1–10: calls a scoring sub-workflow to rate the lead against your rules (1–10) and flag urgency.
• Routes results automatically:
  • High-scoring or urgent → sends a priority Gmail message to the owner with the lead summary and contact details.
  • Mid-scoring → appends the lead and score to a Google Sheets nurture list.
  • Low-scoring / out-of-scope → emails a polite decline message to the enquirer via Gmail.

Use cases

• SaaS operators want instant lead triage instead of manual review.
• Automation engineers need a webhook-driven GPT lead scoring workflow with clear routing logic.
• Teams using Google Sheets for lead nurturing pipelines want automatic scoring-based updates.
