HubSpot contact email validation with Hunter.io

Workflow: HubSpot Contact Email Validation with Hunter.io

Overall Goal

This workflow retrieves contacts from HubSpot that have an email address but haven't yet had their email validated by Hunter. It then iterates through each of these contacts, uses Hunter.io to verify their email, updates the contact record in HubSpot with the validation status and date, and finally sends a summary email notification upon completion.
