Why Use Blind Carbon CopiesWhenever you send an e-mail to more than three or four people, unless it's very important that everyone receiving the e-mail sees the names of everyone else receiving the message, try to use the "BCC:" (Blind Carbon Copy) field rather than the "To:" field when you enter the addresses.
By using the "BCC:" field, you hide those addresses from the recipients of the message. Why do this? Because many viruses and other computer hassles spread themselves by searching through the address books and e-mail archives on the computers they infect. When you send an e-mail to a very long list of recipients, you may be giving a long list of e-mail addresses (some of which may be private) to one of those infected computers. This, in turn, means that everyone on your list may end up receiving spam, viruses, or other malware because just one of the people on the list had an infected computer.
