This workflow automates the creation and updating of HubSpot CRM contacts based on data received from custom webhooks. It validates email addresses using MailboxValidator and assigns contacts to specific lists based on email type.

The workflow begins by triggering a custom webhook, which sends data including an email address. This email is validated using MailboxValidator to ensure its authenticity. If the email is verified, a contact is created or updated in HubSpot CRM with the provided data. The contact is then routed to a specific list based on whether the email is a personal or non-personal address, ensuring organized and targeted contact management.
