We have this need as well. Here is our case study. We send sales order confirmation emails to our clients automatically when we receive an order. This email recap the order detail and client information. We use this email mainly to ask clients to review this information and reply to the email in case of a mistake. The email address we use is generic as we have a team of sales admin who supports these kinds of requests however we want our Area Sales Manager to be aware of any hiccup that can happen with a sale they made. Thus, we would like to CC our Area Sales Manager to these emails since they need to be aware of a reply immediately. The ability to cc someone on an automated email would be really helpful.
