If you set "Bill To Contact" in "To Email" and "All Account Contacts" in "CC Email",
when email notification is sent, email address of "Bill To Contact" is included in CC as well as To.
We have a request to implement the option to exclude "Bill To Contact" in "To Email" from "All Account Contacts" in "CC Email"
so email address of "Bill To Contact" is only included in "To".
