CRM On Premise - Find Contact not used in Email Communcation

Hi Forum,

I have a requirement where I need to give list of the Contacts which has never been used in email communication. i.e not used in either 'From', 'To' , 'CC' or 'BCC' field in email activity record.

As we are on premise deployment I just would like your help to get SQL query to find this list.

Thanks
