How We Saved 22 Hours Weekly: Automating Apollo.io Enrichment with n8n

Manual 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.

At 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.

🛠️ The Automation Architecture

This workflow operates through a four-stage micro-service architecture:

Webhook Event Trigger: Receives raw form submissions.
Apollo.io API Request: Enriches the email with domain-level data, company employee counts, and geographic coordinates.
Data Sanitization: Filters out generic domains (like gmail.com) and normalizes capitalization.
HubSpot Sync: Searches for existing contacts or inserts/updates the deal pipeline.

💻 Step-by-Step Code Configuration

Here is the exact code snippet we use within the JavaScript Code Node in n8n to filter out non-corporate emails before requesting enrichment:

javascript snippet
// Filter out generic email domains
const genericDomains = ['gmail.com', 'yahoo.com', 'outlook.com', 'hotmail.com'];

for (const item of items) {
  const email = item.json.email || '';
  const domain = email.split('@')[1] || '';
  
  item.json.is_corporate = !genericDomains.includes(domain.toLowerCase());
}

return items;

📈 The Business Impact

By deploying this pipeline, our clients have observed:

Zero Data Entry Overhead: Sales reps instantly receive enriched leads.
SLA Drop to Under 10 Seconds: Leads are routed and assigned before they leave the browser.
Improved Lead Conversion: Immediate follow-ups have boosted meeting booking rates by 38%.
