From trigger to booked meeting, fully automated.

Every team building outbound or inbound automation hits the same wall: a new lead arrives and you want to qualify it, route the hot ones to sales and nurture the rest, all without a human babysitting the inbox. This guide shows how to build that exact workflow in n8n, step by step, and then the one-click way to skip the build entirely with PhewDo.

What you are building

The goal is a workflow that runs the second a lead arrives, enriches it, scores it with AI, and routes it based on that score. Here is the shape of it.

New lead arrivesTrigger

A webhook fires when someone submits a form, books a call or replies on a channel.

Enrich the leadHTTP

Call an enrichment API to attach company, role, headcount and tech stack.

Score with AIOpenAI

Ask an LLM to rate intent and fit from 1 to 10 and return a short reason.

Route by scoreIF

Hot leads go to a rep and a sequence, everyone else drops into nurture.

How to build it in n8n

n8n is a great fit for this because every step is a node you can wire visually. Here is the build, node by node.

  1. Webhook node. Add a Webhook trigger and point your form or channel at its URL. Each new lead becomes a JSON payload with name, email and source.
  2. HTTP Request node. Send the email or domain to your enrichment provider and merge the company and role data back onto the item.
  3. OpenAI node. Pass the enriched lead into a prompt like "Score this lead from 1 to 10 for fit and intent, return JSON with score and reason." Parse the result.
  4. IF node. Branch on the score. Send 8 and above down the "hot" path, the rest down "nurture."
  5. Action nodes. On the hot path, post to Slack and enroll the lead in your email or LinkedIn sequence. On the nurture path, add to a drip list.

That is a working pipeline. The catch is everything after you press save: you host n8n, rotate the API keys, watch for failed runs, and rebuild a node every time a provider changes its API. And n8n has no concept of safe outreach pacing, so the sequence step is on you.

Frequently asked questions

Do I need to code to build this in n8n?

No. Every step is a visual node. You will touch a little JSON in the OpenAI and IF nodes, but there is no custom code required for a basic version.

Which AI model should I use for scoring?

Any modern model works. A smaller, cheaper model is usually enough for a 1 to 10 fit-and-intent score, since you are classifying rather than writing long copy.

How is the PhewDo version different?

PhewDo ships the whole pipeline, enrichment, AI scoring, routing and multi-channel outreach with safe pacing, as a single deploy. You do not host anything, manage keys or rebuild nodes when an API changes.
