Email Confirmation of Sales Appt with a Lead

Email Confirmation of Sales Appt with a Lead

I have an inside sales rep who calls leads and tries to create face-to-face sales meetings for me.  When a lead agrees to a meeting I'd like the inside sales rep to use a mail merge template for sending confirmation of the face-toface meeting. 
 
I looked at the Email Templates function. But it appears to be focused on sending out mass mails.  What is the simplest way to send a mail merged email to ONE lead from that person's lead record.  AND:
  **  is there a way to review and modify this email before it gets sent?
  **  is there a way to include a BCC in the template?
