Personalized LinkedIn outreach with GPT-4O, PhantomBuster & Google Sheets
Overview
This sophisticated n8n workflow transforms raw LinkedIn leads into personalized, high-converting connection requests using GPT-4O AI and PhantomBuster automation. The system processes LinkedIn profile data, generates authentic icebreakers, and automatically sends connection requests twice daily, creating a hands-off lead generation machine that maintains human authenticity while scaling outreach efforts.

How It Works
Phase 1: Lead Acquisition & Processing
The workflow begins with scheduled triggers that activate twice daily. Upon activation, the system first cleans up previously processed leads from the source Google Sheet to prevent duplicates. It then retrieves fresh LinkedIn profile data including names, titles, company information, locations, and profile URLs.
Phase 2: AI-Powered Personalization Engine
Retrieved leads are processed in batches of 10 through a sophisticated GPT-4O integration. The AI analyzes each LinkedIn profile and generates personalized icebreakers following a proven template structure. The system is specifically programmed to paraphrase LinkedIn information rather than copy it directly, ensuring messages feel human-written rather than automated.
Phase 3: Data Storage & Campaign Launch
Processed leads with their AI-generated icebreakers are stored in a dedicated Google Sheet for tracking and analysis. The system then aggregates all processed data and triggers a PhantomBuster agent that executes the actual LinkedIn connection requests using the personalized messages.
Phase 4: Cleanup & Notification
After successful campaign launch, the system removes processed leads from the source sheet, sends email confirmation notifications, and prepares for the next scheduled execution cycle.
