Classify & Enrich Contacts with GPT-4o-mini for Sheets, Airtable, HubSpot

This n8n workflow revolutionizes contact management by automatically retrieving new or updated contacts from sources like Google Sheets, Airtable, or HubSpot. It extracts key details such as name, email, and company domain, then performs lookups via external APIs to gather additional data like company info, job titles, and LinkedIn profiles. Data is parsed and cleaned to ensure quality, removing duplicates and invalid entries.

Next, the workflow leverages GPT-4o-mini for intelligent enrichment, analyzing job roles, seniority levels, and inferring interests, intent, persona categories, and engagement scores. This AI step transforms basic contact info into actionable intelligence, enabling precise segmentation.

Validation follows, checking data consistency and applying rules or AI-driven tagging (e.g., 'Decision Maker', 'Technical Buyer'). Finally, enriched contacts are updated back to the source CRM or sheet, with optional Slack/email alerts summarizing changes. Benefits include time savings on manual research, improved lead qualification, and enhanced personalization in sales/marketing campaigns.

Ideal use cases: Sales teams enriching leads for outreach, marketers segmenting audiences, or agencies scaling contact intelligence without custom coding. Supports scheduler/webhook triggers for real-time automation.
