what does bcc mean in email

In email, Bcc stands for "blind carbon copy." When you add recipients in the Bcc field, their email addresses are not visible to the other recipients, including those in the To or Cc fields. This means that the Bcc recipients email addresses remain private, and they will not receive any reply emails from the other recipients, even if they select "Reply all". Bcc can be useful when you want to protect the privacy of the recipients email addresses or when you want to send a clean email without a long list of recipients.
