Qualify leads and draft emails pending human approval

An n8n workflow dedupes and AI-scores leads and drafts personalized emails, sending via Gmail only after human approval.

What they did

The author built LeadFlow AI V1 in n8n as a pipeline. It takes in a lead, validates it and checks for duplicates. AI then qualifies and scores the lead as HOT, WARM or COLD and drafts a personalized email. A person approves the draft before Gmail sends it. Lead data and approval status are logged in Google Sheets.

How it went

The post gives no results or numbers. It is a V1 showcase. A commenter suggested adding a score-reason field next to the rating, so approvers can see the source, reason, next step and draft in one row.

Worth knowing

Approval happens in Google Sheets. A commenter advised keeping it there at first and building a dedicated dashboard only after you know which fields reviewers use.
