Blind Carbon Copy
If you are going to send out emails to a mailing list or even just a few people, you should take great pains to hide the email addresses from everyone on the list.
Usually when someone sends an email to say, four people, they will just list them in the "to:" or "cc:" field. The problem with this practice is simple: everyone who receives the email also receives all of the email addresses. This is wonderful for spammers, but most of us would rather our email addresses were at least somewhat protected.
You can protect your friends email addresses by using the Blind Carbon Copy field. This works just like the Carbon Copy (ccfield, except that the email addresses are not forwarded to each recipient.
Put one email address (perhaps your own) in the "To:" field, and the rest in the "Bcc:" field. When your recipients receive the email, they will see your email address in the "To:" field and their own in the "Bcc:" field. The identity of your other recipients is hidden and they are protected from spammers.
