Benefits of BCC
Although in many situations it may be appropriate to list email
recipients in the To: or CC: fields, sometimes using the
BCC: field may be the most desirable option.

What is BCC?
BCC, which stands for blind carbon copy, allows you to hide recipients
in email messages. Unlike addresses in the To: field or the
CC: (carbon copy) field, addresses in the BCC: field
cannot be seen by other users.
Why would you want to use BCC?
There are a few main reasons for using BCC:
- Privacy - Sometimes it's beneficial, even
necessary, for you to let recipients know who else is receiving your
email message. However, there may be instances when you want to send
the same message to multiple recipients without letting them
know who else is receiving the message. If you are sending email on
behalf of a business or organization, it may be especially important
to keep lists of clients, members, or associates confidential. You may
also want to avoid listing an internal email address on a message
being sent to external recipients.
Another point to remember is that if you use the To: or
CC: fields to list all of your recipients, these same
recipients will also receive any replies to your message unless the
sender removes them. If there is potential for a response that is not
appropriate for all recipients, consider using BCC.
- Tracking - Maybe you want to access or archive
the email message you are sending at another email account. Or maybe
you want to make someone, such as a supervisor or team member, aware
of the email without actually involving them in the exchange. BCC
allows you to accomplish these goals without advertising that you are
doing it.
- Respect for your recipients - Forwarded email messages
frequently contain long lists of email addresses that were CC'd by
previous senders. These addresses are highly likely to be active and
valid, so they are very valuable to spammers. Furthermore, many
email-borne viruses harvest email addresses contained in messages
you've already received (not just the To: and From:
fields, but from the body, too), so those long lists in forwarded
messages pose a risk to all the accounts they point to if you get
infected.
Many people frequently forward messages to their entire address
books using CC. Encourage people who forward messages to you to use
BCC so that your email address is less likely to appear in other
people's inboxes and be susceptible to being harvested. To avoid
becoming part of the problem, in addition to using BCC if you forward
messages, take time to remove all existing email addresses within the
message. The additional benefit is that the people you're sending the
message to will appreciate not having to scroll through large sections
of irrelevant information to get to the actual message.
How do you BCC an email message?
Most email clients have the option to BCC listed a few lines below the
To: field. However, sometimes it is a separate option that is
not listed by default. If you cannot locate it, check the help menu or
the software's documentation.
If you want to BCC all recipients and your email client will not
send a message without something in the To: field, consider
using your own email address in that field. In addition to hiding the
identity of other recipients, this option will enable you to confirm
that the message was sent successfully.
