n8n Lead Routing Automation with Validation & Alerts

n8n Lead Routing Automation with Validation & Alerts

Problem Website leads arrived by email, so managers had to validate, prioritize, and copy every request manually. Incomplete submissions could be missed, while high-budget leads waited too long.

Solution / Workflow I built an n8n workflow that receives each lead through a webhook, validates name, email, and phone, sends incomplete records to manual review with a clear reason, and classifies valid leads by budget. High-value leads trigger an immediate Telegram alert.

What I built • Validation and manual-review routing • Hot/cold classification using explicit business rules • Lead logging and manager alerts • Automated email response structure • Four QA scenarios covering valid, invalid, hot, and cold leads

Tech n8n, Webhooks, JavaScript, Data Tables, Telegram, Gmail

Result Invalid submissions no longer disappear or break the workflow, and priority leads are surfaced immediately instead of waiting for manual inbox review.
