When deciding what to write in an email, it is important to consider your audience.

true

false

That is true.

When you're writing to your teacher at school or your boss at work, you don't use:
"yo"
"wassup"
"hey m8"

You use:
"Dear "
etc. etc. in formal English.

But when you're writing to your friends you might use:
"yo"
"wassup"
"hey m8"

Can you provide the statements?
