How We Saved 22 Hours Weekly: Automating Apollo.io Enrichment with n8n\n\nManual lead entry is the silent killer of sales operations. When new leads submit a form, sales representatives typically spend 5 to 10 minutes digging through LinkedIn, looking up company sizes, and copying data into a CRM. \n\nAt Deepak Automation, we believe human experts should focus on closing deals, not copy-pasting text. In this guide, we show you the exact n8n workflow architecture we built to enrich inbound leads using Apollo.io and push them directly to HubSpot.\n\n---\n\n## 🛠️ The Automation Architecture\n\nThis workflow operates through a four-stage micro-service architecture:\n\n1. Webhook Event Trigger: Receives raw form submissions.\n2. Apollo.io API Request: Enriches the email with domain-level data, company employee counts, and geographic coordinates.\n3. Data Sanitization: Filters out generic domains (like gmail.com) and normalizes capitalization.\n4. HubSpot Sync: Searches for existing contacts or inserts/updates the deal pipeline.\n\n---\n\n## 💻 Step-by-Step Code Configuration\n\nHere is the exact code snippet we use within the JavaScript Code Node in n8n to filter out non-corporate emails before requesting enrichment:\n\njavascript\n// Filter out generic email domains\nconst genericDomains = ['gmail.com', 'yahoo.com', 'outlook.com', 'hotmail.com'];\n\nfor (const item of items) {\n const email = item.json.email || '';\n const domain = email.split('@')[1] || '';\n \n item.json.is_corporate = !genericDomains.includes(domain.toLowerCase());\n}\n\nreturn items;\n\n\n---\n\n## 📈 The Business Impact\n\nBy deploying this pipeline, our clients have observed:\n- Zero Data Entry Overhead: Sales reps instantly receive enriched leads.\n- SLA Drop to Under 10 Seconds: Leads are routed and assigned before they leave the browser.\n- Improved Lead Conversion: Immediate follow-ups have boosted meeting booking rates by 38%.\n\nWant to see how this fits into your own stack?
