However, this sort of thing is ethically problematic: you should have a good and ethical reason for not letting the primary addressee know that the email is being copied to someone else, since blind copying is basically a form of deception. You can blind copy an email to someone without the other addresses knowing that you did so to make a third party aware of an important issue, or to establish an independent confidential record of your email. Some of the ways that the BCC field can be used are listed below: If you put addresses in the BCC field of an email it will be secretly copied to those addresses, and none of the other addresses in the To, CC, or BCC fields will know about it because the BCC field is not displayed on incoming messages. It turned out that people liked this feature so much they built it into email. Because there was no way the official addressees could know about these extra copies, they were called "blind carbon-copies" (BCC). Occasionally, by accident or design, an extra carbon copy would be given to someone not on the official CC carbon copy address list.

The top carbon copies always looked much crisper than the lower copies, as the force of the typewriter key strike dissipated through the layers. The top paper got the typewriter ink and looked the best. You could get two, three, and four-layer carbon copy paper, and even some very thin six-layer paper. When you were finished typing a page, you would separate out the paper and throw away the carbon sheets, almost always getting some of the black carbon all over your hands. Between each layer of paper was a thin sheet with carbon on the bottom side, so that when the typewriter keys hit the paper, the impact made a "carbon copy" of the letter on the paper sheet underneath.
BLIND COPY AND BLIND WRITE MANUAL
The simple term "carbon copy" comes from the days of manual typewriters, when copies were made by typing on paper with several layers. The story of the blind carbon copy function is another example of real-world processes imaging themselves in the virtual world. You can blind carbon copy (BCC) people on an email without the main addressees knowing about it.
