Automated B2B Lead Generation & Cold Emails with OpenAI, Apify, Gmail & Telegram

🧩 Description

A customized n8n workflow inspired by the Lead Generation Agent template.
It automates B2B lead scraping via Apify, extracts contact emails with AI, sends cold emails via Gmail, and logs every interaction in Google Sheets with Telegram alerts for live monitoring.

🧠 How It Works

This workflow automates the entire B2B lead generation and outreach process from data collection to email delivery.
Once you enter your search keyword and location, the system scrapes business details using Apify, filters valid websites, and extracts email addresses with AI. Each lead is then enriched and logged in Google Sheets.

The workflow automatically composes a personalized cold email based on your preferred tone (friendly, simple, or professional) and sends it through Gmail with short delays between each message to avoid spam filters.
You’ll also receive Telegram notifications to monitor progress and any leads that fail to send.

⚙️ Setup Steps

Clone the workflow into your n8n instance.
Add your API credentials:
Apify API Token
OpenAI (or Gemini) API Key
Google Sheets & Gmail account connections
Telegram Bot Token + Chat ID (optional)
Open the Form node or Manual Trigger, and set your search criteria (e.g., “marketing agencies in London”).
Configure your Google Sheet — make sure the columns match the node mapping.
Adjust the AI prompt in the OpenAI node if you want a different tone or style for your emails.
Run the workflow manually to test one or two leads first.
Once confirmed, activate scheduling or keep it manual for on-demand lead generation.
