If I understand your question, you are talking about where you CCed someone in an email you sent out OR you sent them a copy of an email that you already sent out . In any case , you would say to them, " I sent you a copy of my email."

to simplify, you can say: "you were included in my email" or "you were CC'ed in my email" if you were the one who sent the email to someone and had another one copied in it. :)

Hi! you can simply say "i loop you in the email that i sent" cowboy...

Do you mean, have you got my email or have you got a copy of my email?

right: It is not correct to say "You are in copy of my email". Do you mean, 'You answered on my e-mail?'?
