HubSpot Contact Email Validation with Hunter.io

This workflow automates email validation for HubSpot contacts lacking prior Hunter.io verification. It starts with a manual trigger, fetches contacts having an 'email' property but no 'hunter_email_validation_status', then loops through each one. For every contact, it verifies the email using Hunter.io's Email Verifier and patches the HubSpot record via HTTP request to add validation details like status and date.

Upon processing all contacts, it sends a summary email notification. This ensures data hygiene by flagging invalid emails early, improving campaign deliverability and reducing bounce rates.

Benefits include significant time savings for sales/marketing teams manually checking emails, enhanced CRM accuracy, and scalability for large contact lists. Ideal use cases: Pre-campaign cleanups, lead enrichment in sales pipelines, or periodic data maintenance in CRMs.
