Both the Standard and PRO versions of EmailMerge support CC and BCC fields.
You can CC and BCC by entering the contacts on your composed email in the respective fields (Cc... and Bcc...). After merging the merged copies of the emails will also be sent to the people being CC'd and BCC'd.
Note: EmailMerge Pro also supports sending personalized CC and BCC contacts. For example, if you would like to send a personalized email to Anna and CC Ben and send another personalized email to Patricia and CC Tom, this feature is only available to EmailMerge Pro .
