Whenever a new customer is added in Books we add the contact to Campaigns.  This is easy to do via sync.

We need to send an internal email when the contact is added in Campaigns.  This is also easy to do with "Internal Notification Email" automation.

Question is: how to add information about the new contact (name, address, custom fields) to the email subject and body.

(Like using ${CONTACT.CONTACT_DISPLAYNAME} in zoho books)
