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

This n8n workflow automates the process of B2B lead generation, enrichment, and personalized cold email outreach. It leverages AI to extract information, generates email content, and sends emails, with human approval steps integrated via Telegram.

What it does

This workflow streamlines your lead generation and outreach efforts by:

1. Triggering from a Form Submission: Initiates the workflow when a new form is submitted, likely containing initial lead data.
2. Extracting Information with AI: Uses an AI-powered Information Extractor (likely Apify or a similar service via HTTP Request) to parse and structure data from the initial lead information.
3. Enriching Lead Data (via HTTP Request): Makes an HTTP request to an external API (e.g., Apify) to gather more detailed information about the company or contact.
4. Filtering Leads: Evaluates the enriched data using an "If" node to determine if the lead meets specific criteria for outreach.
5. Generating Personalized Email Content with AI: For qualified leads, it uses an OpenAI Chat Model to craft a personalized cold email based on the extracted and enriched information.
6. Human Review via Telegram: Sends the generated email content to a Telegram chat for human review and approval.
7. Conditional Email Sending: Checks the approval status from Telegram.
8. Sending Cold Emails: If approved, sends the personalized cold email via Gmail.
9. Waiting for Follow-up: Includes a "Wait" step, likely to schedule a follow-up action after a specified period (not fully implemented in the provided JSON, but indicated by the node).
10. Updating Google Sheets: Records the lead information and outreach status in a Google Sheet.
