n8n AI Lead Qualification: Lusha + Claude Scoring & Gmail

Instant AI lead qualification from your n8n form—then personalized Gmail drafts, automatically

This n8n workflow turns your ICP inputs into a fully automated pipeline: it collects criteria via an n8n form, finds matching contacts in Lusha, scores them with Claude (via OpenRouter), logs results in Google Sheets, and generates personalized Gmail outreach and follow-ups on a daily schedule.

What this workflow does

• Collects ICP criteria from an n8n form submission (industry, seniority, location, company size, minimum score, and an optional ICP description).
• Translates inputs into Lusha filters by converting the form selections into Lusha filter IDs and building a Lusha contact search request payload.
• Searches and enriches leads in Lusha—if matches are found, it fetches full contact and company details.
• Scores each lead with Claude (Claude 3.5 Sonnet via OpenRouter) on a 1–10 scale, assigns Qualified/Unqualified based on the minimum score, and returns a short reason + recommended action.
• Writes results to Google Sheets, updating AI scoring fields—or shows a “No Leads Found” completion page when there are zero matches.
• Runs daily outreach cycles: at 9 AM, it reads the sheet, selects qualified leads not yet emailed, drafts (or sends) personalized cold emails, and updates outreach tracking; at 10 AM, it drafts follow-ups for leads due for follow-up with pacing limits.

Use cases

• SaaS teams qualifying ICPs and generating timely cold outreach without manual research.
• Automation engineers building an AI-assisted pipeline from form → enrichment → scoring → Gmail follow-up.
• Operators who want daily lead scoring in Google Sheets plus controlled email cadence.
