Reported experience

  1. 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.

  2. 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.

  3. 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.

Example prompts

Try with n8n
Build me an n8n workflow that takes new leads from [source], removes duplicates, scores each one 1-10 against this ideal customer profile: [description], and drafts a personalized email for each qualified lead. Save the drafts and scores in [Sheet or Airtable] and notify me to approve. Only send through Gmail after I approve each draft, and show me the email before anything is sent.
