The wpcrm_system_create_contacts_email_key_status filter is used along with the wpcrm_system_create_contacts_email_key filter.

By default, the wpcrm_system_create_contacts_email_key_status filter returns ‘publish’, but you can modify this to other valid post_status values to include or exclude certain contacts from the search.

This means that if you want to include all contacts (including those who are in a “draft” or other that “publish” status), you can return “any” with this filter.
