HubSpot Contact Enrichment with Explorium

Automatically enrich new HubSpot contacts with professional email addresses and phone numbers using Explorium's B2B intelligence platform.

Template

Download the following json file and import it to a new n8n workflow:

hubspot_flow.json


Overview

This n8n workflow monitors your HubSpot instance for newly created contacts and automatically enriches them with additional contact information. When a contact is created, the workflow:

  1. Detects the new contact via HubSpot webhook trigger
  2. Retrieves recent contact details from HubSpot
  3. Matches the contact against Explorium's database using name, company, and email
  4. Enriches the contact with professional emails and phone numbers
  5. Updates the HubSpot contact record with discovered information

This automation ensures your sales and marketing teams have complete contact information, improving outreach success rates and data quality.

Key Features

  • Real-time Webhook Trigger: Instantly processes new contacts as they're created
  • Intelligent Matching: Uses multiple data points (name, company, email) for accurate matching
  • Comprehensive Enrichment: Adds both professional and work emails, plus phone numbers
  • Batch Processing: Efficiently handles multiple contacts to optimize API usage
  • Smart Data Mapping: Intelligently maps multiple emails and phone numbers
  • Profile Enrichment: Optional additional enrichment for deeper contact insights
  • Error Resilience: Continues processing other contacts if some fail to match

Prerequisites

Before setting up this workflow, ensure you have:

  1. n8n instance (self-hosted or cloud)
  2. HubSpot account with:
    • Developer API access (for webhooks)
    • Private App or OAuth2 app created
    • Contact object permissions (read/write)
  3. Explorium API credentials (Bearer token)
  4. Understanding of HubSpot contact properties

HubSpot Requirements

Node Descriptions

  1. HubSpot Trigger: Webhook that fires when new contacts are created
  2. HubSpot Recently Created: Fetches details of recently created contacts
  3. Loop Over Items: Processes contacts in batches of 6
  4. Explorium Match Prospects: Finds matching person in Explorium database
  5. Filter: Validates successful matches
  6. Extract Prospect IDs: Collects matched prospect identifiers
  7. Enrich Contacts Information: Fetches emails and phone numbers
  8. Enrich Profiles: Gets additional profile data (optional)
  9. Merge: Combines all enrichment results
  10. Split Out: Separates individual enriched records
  11. Update HubSpot: Updates contact with new information

Data Mapping Logic

The workflow maps Explorium data to HubSpot properties:

Explorium DataHubSpot PropertyNotes
professions_emailemailPrimary professional email
emails[].addresswork_emailAll email addresses joined
phone_numbers[].phone_numberphoneAll phones joined with commas
mobile_phonephone (fallback)Used if no other phones found

Data Processing

The workflow handles complex data scenarios:

  • Multiple emails: Joins all discovered emails with commas
  • Phone numbers: Combines all phone numbers into a single field
  • Missing data: Uses "null" as placeholder for empty fields
  • Name parsing: Cleans sample data and special characters

Usage & Operation

Automatic Processing

Once activated:

  1. Every new contact triggers the webhook immediately
  2. Contact is enriched within seconds
  3. HubSpot record is updated automatically
  4. Process repeats for each new contact

Manual Testing

To test the workflow:

  1. Use the pinned test data in the HubSpot Trigger node, or
  2. Create a test contact in HubSpot
  3. Monitor the execution in n8n
  4. Verify the contact was updated in HubSpot

Monitoring Performance

Track workflow health:

  1. Go to Executions in n8n
  2. Filter by this workflow
  3. Monitor success rates
  4. Review any failed executions
  5. Check webhook delivery in HubSpot

Troubleshooting

Common Issues

Webhook not triggering

  • Verify webhook subscription is active in HubSpot
  • Check the webhook URL is correct and accessible
  • Ensure workflow is activated in n8n
  • Test webhook delivery in HubSpot developers portal

Contacts not matching

  • Verify contact has firstname, lastname, and company
  • Check for typos or abbreviations in company names
  • Some individuals may not be in Explorium's database
  • Email matching improves accuracy significantly

Updates failing in HubSpot

  • Check API token has contact write permissions
  • Verify property names exist in HubSpot
  • Ensure rate limits haven't been exceeded
  • Check for validation rules on properties

Missing enrichment data

  • Not all prospects have all data types
  • Phone numbers may be less available than emails
  • Profile enrichment is optional and may not always return data

Error Handling

Built-in error resilience:

  • Failed matches don't block other contacts
  • Each batch processes independently
  • Partial enrichment is possible
  • All errors are logged for review

Debugging Tips

  1. Check webhook logs: HubSpot shows delivery attempts
  2. Review executions: n8n logs show detailed error messages
  3. Test with pinned data: Use the sample data for isolated testing
  4. Verify API responses: Check Explorium API returns expected data

Best Practices

Data Quality

  1. Complete contact records: Ensure name and company are populated
  2. Standardize company names: Use official names, not abbreviations
  3. Include existing emails: Improves match accuracy
  4. Regular data hygiene: Clean up test and invalid contacts

Performance Optimization

  1. Batch size: 6 is optimal for rate limits
  2. Webhook reliability: Monitor delivery success
  3. API quotas: Track usage in both platforms
  4. Execution history: Regularly clean old executions

Compliance & Privacy

  1. GDPR compliance: Ensure lawful basis for enrichment
  2. Data minimization: Only enrich necessary fields
  3. Access controls: Limit who can modify enriched data
  4. Audit trail: Document enrichment for compliance

Customization Options

Advanced Configuration

Custom Field Mapping

Modify the Update HubSpot node to map to custom properties:

// Example custom mapping
{
  "custom_mobile": "{{ $json.data.mobile_phone }}",
  "custom_linkedin": "{{ $json.data.linkedin_url }}",
  "enrichment_date": "{{ $now.toISO() }}"
}

Conditional Processing

Add logic to process only certain contacts:

  • Filter by contact source
  • Check for specific properties
  • Validate email domains
  • Exclude test contacts
