This page describes the email recipient fields as they appear in your Compose mail screen.
To: The
field where you type the email address that you want the message sent
to.
You must specify at lease one recipient in the To field. If you leave
this field blank, an error message appears when you press Send.
Cc: Carbon
Copy. The message is sent to anyone listed in the Cc: field.
All other recipients of this message can see the name of the person
you are copying the message to.
Bcc: Blind
Carbon Copy. The message is sent to anyone listed in the Bcc: field.
Other recipients in the To and Cc fields cannot
see the name of the person you are blind copying the message to.
For example, if you send a message to billdoe@email.com and a blind
copy to georgedoe@email.com, billdoe sees only his name as the recipient;
however, georgedoe (the recipient of the blind copy) receives a copy of
the message and can see that you have also sent the message to billdoe.
