I need to send a mass update to a group of Contacts.  It's important that when a Contact replies to the email that they can click Reply All and reply to the Sales Manager as well as the Customer Service Rep.  It's important that both the Sales Manager and the Customer Service rep receive replies.

If we were using Outlook we'd add the Contact in the TO field and the Customer Service Rep in the CC field.

How would I achieve this in the CRM?
