The answer to a crossword clue referencing content surreptitiously added to an email is often “BCC.” This abbreviation stands for Blind Carbon Copy, a method of sending email where recipients listed in the BCC field are not visible to other recipients, ensuring their email addresses remain private. For instance, if an email is sent to addresses in the “To:” and “CC:” fields, as well as a separate address in the “BCC:” field, those in the “To:” and “CC:” fields will not be able to see the address listed in the “BCC:” field.
Utilizing this feature offers significant advantages in maintaining privacy and managing communication. It is particularly important when sending group emails to individuals who may not know each other or when a sender wishes to avoid sharing a recipient list. This practice helps prevent unwanted replies to all and protects recipients from potential spam or security threats that could arise from widespread email address dissemination. Historically, this mechanism emerged as a crucial tool in email communication as a response to growing concerns surrounding data privacy and the potential for misuse of contact information.
