How to use the term "carbon copy" in business emails?

How does one use the term "carbon copy" in an email setting?
Some options that come to mind are:

• In carbon copy is my manager.
• I'm leaving my manager in carbon copy.
• My manager is in carbon copy.

Alas, none of these feel right to me. What's the proper way of using this term to convey the idea that someone's email address is in the box named "Cc"?

Solution 1:

If you don't wish to use "cc" (as per your comment on Jon Hanna's answer it means something else in your native language) you can just use the verb to copy:

1.3 (copy something to) Send a copy of a letter or an email to (a third party)

‘I thought I'd copy to you this letter sent to the PR representative’

1.4 (copy someone in) Send someone a copy of an email that is addressed to a third party.

‘I attached the document and copied him in so he'd know it had been sent’

I've also seen usage without the "to" or "in", and this is the usage I tend to use myself:

I've copied my manager as he will need to provide approval

As per Jon Hanna's second example, you can also use this parenthetically:

My manager (copied) will need to provide approval

My manager (copied in) will need to provide approval

As per MT_Head's comment you may also see "copy on", although to me it sounds more natural to use "copy in on":

I've copied my manager on this email as...

I've copied Steve in on this email because...

I would advise against including the word "carbon"; I've not seen it in common usage.

Solution 2:

It tends to be used as a verb, and abbreviated:

I've CCed my manager.

Or parenthetically in a sentence about whatever reason you have for saying you've done so.

My manager (CCed) will have to approve this before I can proceed.

Even if you don't like using such abbreviations, I'd recommend them in this case because I think the metaphor behind the term is being lost in that some people would know CC as the term for including another recipient on an email, but not "carbon copy" as the source of the abbreviation.

Solution 3:

There are lots of answers using the verb copy here, but an option you might consider is a more direct comment that someone is included in the e-mail/conversation:

I've included my manager in this e-mail/conversation...

Or even parenthetically:

...my manager (included in this e-mail)...
