Emails are something people rely on as a way of communication

Emails are something people rely on as a way of communication. Emails are good because they can deliver news to someone across the world in a few seconds! Another thing that is good is having proper email etiquette.
Addressing:
The heading of an email usually starts with a To:
Besides “To”. you could also use “BCC” or “CC”
“BCC” or, blind carbon copy means that no one but the sender can see the list of BCC recipients. BCC is used when a sender wishes to send an email to more than one recipient without revealing the other recipients to each other.
“CC” or, carbon copy is a way of sending additional copies of an email to other people. Unlike BCC, the CC list is visible to all other recipients.
