Generate Personalized Cold Emails from LinkedIn Jobs with GPT-4o and Gmail

LinkedIn Job-Based Cold Email System

Most outreach tools rely on generic lead lists and recycled contact data.

This workflow builds a live, personalized lead engine that scrapes new LinkedIn job posts, finds company decision-maker emails, and generates custom cold emails using GPT — all fully automated through n8n.

How It Works

Schedule Trigger runs every morning at 08:00. Apify LinkedIn Scraper collects new “Marketing Manager” jobs in Belgium. Remove Duplicates ensures each company appears only once. Filter Staffing excludes recruiters, HR agencies, and interim firms. Save Useful Infos extracts core company data — name, domain, size, description. Filter Domain & Size keeps valid websites and companies under 100 employees. Anymailfinder API looks up CEO, Sales, and Marketing decision-maker emails. Merge + If Node validates email results and removes invalid entries. Split Out + Deduplicate ensures unique, verified contacts. Extract Lead Name (Code Node) separates first and last names. Google Sheets Node appends all enriched lead data to your master sheet. GPT-4o (LangChain) writes a 100–120 word personalized cold email. GPT-4o (LangChain) creates a short, casual subject line. Gmail Draft Node builds a ready-to-send email using both outputs. Wait Node loops until all leads are processed.
