Why Set Up Automatic BCC in Apple Mail?
The Mac’s Mail app keeps a copy of every email message you send in the Sent folder, but some users prefer a more permanent and regular archive of their sent messages. If you have multiple email accounts and want to use one to collect copies of all your correspondence, it’s easy to BCC that email address every time you send a message. While you can do this manually, typing an email address into the BCC field of each message, it’s even easier to set up Mail to do it for you automatically. This function works if you need to automatically BCC any email address, such as your boss, on all your messages.
