AI Lead Qualification n8n: GPT-4.1 Mini + Telegram + Sheets

Turn every inbound lead into an instant, AI-qualified sales signal—automatically

This AI Lead Qualification n8n workflow accepts leads through a POST webhook, optionally fetches and cleans the company website, then uses OpenAI (GPT-4.1 mini) to generate a structured qualification report with a score and outreach copy. If the lead scores 70+, it sends a Telegram high-priority alert—and logs everything to Google Sheets.

What this workflow does

• Receives inbound leads via webhook (name, email, company, website, phone, message, etc.).
• Normalizes lead fields into a consistent structure for downstream processing.
• Optionally downloads and cleans website HTML, trimming it into a limited text payload suitable for AI analysis.
• Qualifies and scores the lead with GPT-4.1 mini using both the lead details and cleaned website content to produce:
  • lead qualification report
  • score & priority
  • intent + recommended follow-up
  • outreach messages
• Sends Telegram alerts for high-priority leads when the AI lead score is 70 or higher.
• Appends results to Google Sheets, storing both the original lead data and the AI-generated qualification + outreach fields.

Use cases

• SaaS teams that want faster lead triage from a contact form or landing page submission.
• Automation engineers building an n8n lead routing system that combines CRM-like scoring with website context.
• Founder-led growth teams needing actionable outreach drafts and instant notifications for top prospects.

Technical details

• n8n nodes: Webhook, If, Set, Code, Merge, Telegram
• AI: OpenAI credential configured for GPT-4.1 mini
• Notifications: Telegram bot credential + target chat for high-priority alerts
• Data logging: Google Sheets OAuth2 with spreadsheet/document ID, sheet name, and column headers aligned to appended fields

Great for n8n automation workflows where you need AI lead qualification, Telegram-driven follow-up, and Sheets-based record keeping—all in one flow.
