Automated n8n Lead Generation & Outreach Agent

Project: Build Automated Lead Generator Agent on n8n

Objective
Develop a fully automated Lead Generation & Outreach Agent on n8n, that connects to data enrichment tools (Apollo, Lusha, etc.), collects potential client contacts (B2G & B2B), stores them in Google Sheets, and automatically sends introduction messages through WhatsApp Cloud API, Email, or LinkedIn InMail.
The system should monitor engagement (delivered / read / opened / replied), notify me via WhatsApp if there’s no reply after 48 hours, and update all activity logs in a database or CRM.

The goal is to create a scalable outbound automation system tailored for Managed Services (Cybersecurity provider) — focusing on government and enterprise accounts


The workflow will include 9 modular workflows on n8n, fully automated and interconnected through database triggers, Google Sheets, and webhooks.
