AI Lead Qualification

A lead-intake system that scores every inbound enquiry 0–100 on real buying intent, routes hot leads to the sales team with an urgency-coded email, saves everything to a CRM sheet automatically, and replies to the lead instantly so no one is left wondering if their message went through.

01

The Challenge

Manually triaging inbound enquiries means hot, ready-to-buy leads sit in the same inbox as browsers and tire-kickers — and the first team member to check email decides who gets followed up on today versus next week.

02

The System

We built an n8n workflow that captures a lead from a form or webhook, scores it with Google Gemini against real buying-intent criteria rather than just form completion, classifies it HOT/WARM/COLD, saves the full record to a CRM spreadsheet, sends the sales team a color-coded priority email, and auto-replies to the lead within seconds.

03

Guardrails

The scoring prompt uses explicit buying-intent criteria.

Every classification and source message is retained in the CRM.

Automation prioritizes leads; it does not invent missing details.

Let's build something people actually use.
