Automated lead generation & contact enrichment with Hunter.io and Perplexity AI

Who is this for?

This template is ideal for B2B founders, solopreneurs, growth marketers, SDRs, or anyone looking to scale their lead generation and enrichment with no-code tools to low-code tools.

Whether you're building your first lead pipeline or upgrading a manual spreadsheet, LeadAIgen automates the entire discovery → enrichment → logging process using AI and verified email data.

What problem does this solve?

Lead sourcing and enrichment are time-consuming, inconsistent, and often require multiple tools or manual scraping.

This workflow solves that by chaining AI + contact discovery, validating everything, and storing clean, structured data in Google Sheets — ready for outreach or CRM sync.

What this workflow does:

✅ Accepts an industry/topic prompt via chat trigger or Telegram,
🤖 Uses OpenRouter (Perplexity) to find 15 relevant companies with domains,
📤 Parses the results, filters duplicates based on your Google Sheet,
📩 Enriches each domain with up to 3 real personal emails using Hunter.io,
💡 If no emails found → Fallback AI tries to locate general email info,
📊 Updates your Google Sheet with all valid enriched leads (status: “Enriched”),
🔁 Runs in safe batches of 10 to protect your API limits,
🛠️ Includes logic to clean data, validate JSON, and slice leads.

Setup:

• Create Google Sheets, Hunter.io, and OpenRouter credentials in your n8n instance
• Import the JSON workflow
• Set your OpenRouter model (default = Perplexity Sonar Large)
• Connect your Google Sheet (must contain a header row with Domain, Status, etc.)
• Paste your Hunter API key into the Hunter.io node
• (Optional) Add Telegram Bot trigger to chat with your lead generator

🗒 Color-coded workflow notes:
