When email replaced traditional forms of office communication, it took on the existing language of paper-based memoranda. Office assistants used to type correspondence on carbon-backed paper so that a carbon copy was automatically made, which could then be sent to a second recipient. It eliminated the need to type the same document multiple times.
The term carbon copy – or more commonly, “CC” – is now an integral part of email lingo. And while there isn’t a handbook on how and when to use it, there are some best practices that are worth bearing in mind before filling out the CC field and clicking “send.”
How to use CC in Gmail
Using CC in current email language means you’re sending an email not only to the primary recipient in the “To” field, but also to one or more secondary recipients. In Gmail, you can CC up to 100 recipients in any one email.
To complete the CCfield in Gmail:
- Click Compose to open a new message.
- Complete the To field by inserting the primary recipient email address.
- Click CC in the top right of the email composer.
- Insert the secondary recipients’ email addresses.
Once you’ve clicked Send, your email will be sent to both your primary recipient in the To field, and to any email recipients you’ve included in the CC field. Every recipient will be able to see all of the other email addresses, so make sure you have consent to share your contacts’ details.
When to use cc in an email
While CC is a useful tool both for saving time and improving communications, it’s often used too liberally, without proper consideration to some basic communication etiquette. As such, our list of when to use CC is relatively short:
When you want to keep recipients in the loop
Use caution when keeping people “in the loop.” If you use it to excess, then you risk inundating your recipients with too many emails that they simply won’t read.
Think about whether each recipient really needs to be copied. Does the email contain information that they need, or are you just adding yet another email to their inbox?
As a general rule, we’d suggest that people who need to be kept in the loop are:
- Managers or colleagues who specifically ask to be CC’d on all or specific communications.
- Members of a team who need to be kept abreast of a project.
When you’re introducing a contact
When you’re emailing someone to introduce them to another contact, you want both parties to see the email so that they can continue the conversation afterwards. It’s up to you whether you add the new contact in the To or the CC field here, although using CC is perfectly acceptable.
When not to use CC in an email
Bulging inboxes can be a real problem for efficiency, and it’s natural for people to prioritize more pressing emails over correspondence they’re merely CC’d on. If you routinely CC one of your contacts on your broader correspondence, before too long, they’ll stop reading the emails altogether. This could result in them missing out on some important information along the way.
Use caution with this function so that you’re not unnecessarily CC’ing people and inundating them with more mail than they need.
When you don’t have appropriate consent
When used liberally and unthinkingly, CC’ing can cause unintended problems.
Say you’ve been in email communication with a colleague and then suddenly decide that another colleague might also benefit from being included in the thread. Before simply CC’ing them on your next reply, make sure you ask the permission of both parties first. There could be sensitive information deep in the existing thread that the new contact shouldn’t see.
When you’re expecting a response or action
Consider only CC-ing recipients from whom you don’t expect a response or a direct action – in fact, most email recipients automatically assume no action is needed on their part if they’re only CC’d. If you do want a recipient to respond or act, then technically they should be put in the To field.
Before you hit send, look at your CC field and think about what you’re expecting from each of those recipients. Depending on your answers, consider moving appropriate contacts into the To field instead.
When you want to embarrass someone or prove a point
It’s not unusual for people to use the CC field for cynical reasons.
You may have received an angry email from a colleague with your boss copied in. Or you may have been called out by your manager for an action you’ve taken and been tempted to prove that they had already been copied into the relevant correspondence.
Using CC for passive-aggressive or point-scoring reasons is not good practice and should be left alone.
When you want to copy in many recipients
Overpopulating the CC field can be extremely distracting to any recipient opening a new email, so ideally keep the CC field to no more than three or four recipients. Any more than this, and you should consider doing a mail merge or using newsletter software such as Mailchimp.
Use it sparingly
Most of us get on with our day-to-day email correspondence without giving it too much thought. We use CC regularly to cover our backs and to ensure that everyone is kept “in the loop” whether they need to be or not.
But next time you compose an email, take a minute to consider whether CC-ing is helpful or necessary. CC is a very useful tool, but only when used sparingly and with some consideration.
