Hide Emails Related List for certain contacts

Hide Emails Related List for certain contacts

Hello,

We would like to hide Email Related List for certain Contacts in Zoho CRM, so that salespeople cannot see email correspondence between company management and our vendors that are in the CRM.  The contact record doesn't need to be hidden, just the emails that would show up in the emails related list.  

All emails sent by management to CLIENTS in CRM need to remain visible to salespeople. 

Thanks,

Jay Ashland
