Tip 1. Subject, Cc: and Bcc:
When you write an email, at the top is a field called "Subject:". The subject tells recipients what your message is about, without reading the whole message. It also helps them organize their emails. Always include a subject, something meaningful like "My Order No. 12345 For Furniture" or "Homework Assignment: Present Perfect". Don't just write "Your Email" or "Letter". Subjects like those are not very helpful. Also, if you include a subject and the recipient replies by clicking on "Reply", your subject is automatically added to the reply (with the expression "Re:", which means "about").
Two more fields at the top of your email are "Cc:" (carbon copy) and "Bcc:" (blind carbon copy). Any email address you add to the Cc: box will receive a copy of the message, and the original person you are writing to (the To: field) will see the email address that you sent a copy to. Any email address you add to the Bcc: field will also receive a copy of the message, but this time the original person you are writing to will not see this. S/he will not even know that you sent a copy to someone.
