How to do it yourself

Our suggested steps. The company didn't publish theirs.

  1. 1

    Put all leads from every site/form into one Supabase table.

  2. 2

    In n8n, send each new lead to Claude with the prompt below to score and tag it.

  3. 3

    Route hot leads to your phone, the rest to an email sequence.

  4. 4

    Add a daily uptime/error check for your sites.

  5. 5

    Review the lead scores weekly and tweak the prompt.

The instructions to give the AI

Paste this into Claude (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.

This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.

Agent instructions (prompt)

Score this lead 1-10 for [business list]. Say which business it fits, why, and the next action (call now / nurture / ignore). Return JSON: {business, score, reason, action}.
Lead:
[paste]

[Highlighted] = replace with your own details before you run it.

What you should get back: "8/10 — fits the cleaning business: 3 locations, hiring. Next: call today."
