A fully autonomous outreach engine that runs 24/7.
The project
The client needed a fully automated sales outreach system that could handle the entire lead lifecycle — from initial discovery through to scoring, outreach, response handling, re-engagement, and analytics — without any human intervention.
The complexity here was significant: the system needed to understand lead intent using AI, generate personalised emails for each lead, parse replies intelligently via Gmail, update scores dynamically based on engagement, and report on everything daily.
I built a 4-workflow n8n system — each workflow handling a distinct phase of the lead lifecycle, all interconnected and running autonomously around the clock.
How it works
The supplied project combines hourly outreach, Gmail response handling, re-engagement scheduling, and daily reporting. The key mechanisms below are the original build details.
Hourly trigger fetches top leads, retrieves product data, gets current outreach templates, runs AI intent classification, aggregates variables, generates personalised outreach emails, sends them, and logs each outreach action automatically.
Each lead is run through an AI node that classifies their intent level — hot, warm, or cold — based on their data profile and previous correspondence. This determines which outreach template and tone is used.
AI generates a unique outreach email for each lead — pulling in their name, product interest, prior correspondence, and intent score. No two emails are identical. Sent via Gmail integration.
Gmail Webhook fires when a reply arrives — AI classifies the response type, routes to the appropriate branch, and updates the lead's score and status in real time.
Every interaction — send, open, reply, click — updates the lead's score automatically. Scores drive future outreach timing and tone. High-scoring leads get escalated to a human sales rep notification.
Leads that go cold trigger a separate re-engagement workflow — AI generates a new angle email, applies score decay logic, and schedules follow-ups at optimal intervals to revive dormant prospects.
Daily trigger collects all active leads, processes results in batches, calculates score decay, updates lead scores, generates an AI analytics report, and sends it via email — giving complete visibility without manual reporting.
The four workflows share data through a central lead database — each workflow reads and writes lead status, scores, and history. The system self-optimises based on what's working across the entire pipeline.
Tools & stack
The project uses the original n8n, AI scoring, Gmail, reporting, scheduling, and autonomous workflow components documented in the supplied case study.
“This is the most sophisticated automation Samuel has built for us — and it runs flawlessly. Leads get fetched, scored, emailed, and followed up with automatically. When someone replies, the system classifies it and updates everything instantly. Our sales team now only touches the hottest leads.”AI Lead Scoring & Outreach Clientn8n Multi-Workflow Automation System
