If you’ve been using email clients for some time, you may already aware that you have the option of sending email to multiple recipient using to:, cc: and bcc:.
cc: means ‘carbon copy’ – is a copy given to another recipient beside the person you’re sending the email to. For example, if you are writing an email inquiring about the price of a particular product, naturally you’ll send it to [email protected], and then you might want to send a carbon copy to your supervisor – [email protected], telling him that you’re doing your job.
so when the sales department in the other company responded, your supervisor will be able to read the reply as well. So everybody in the cc list is able to know each other email address when they receive it.
bcc: stands for blind carbon copy – basically is the same with cc: but with a little twist, the bcc: receiver just receive a copy of the email, and he can’t read other email addresses in the list. So in a nutshell, bcc offers more privacy than cc because the email address of the recipient is protected from each other.
hope that helps clears up some questions
