What Does “Cc” in an Email Mean?

If you’ve ever received or sent an email, you’ve probably seen the “Cc” field. But what does it mean? Cc stands for “carbon copy,” and it’s a way to send a copy of an email to one or more additional recipients without them being the primary recipient. In this blog post, we’ll explore the ins and outs of the Cc field, including its history, how it works, and best practices for using it.

History of the Cc Field

The Cc field has been around since the early days of email. In the early 1970s, when email was first developed, it was primarily used by academics and researchers to communicate with one another. At that time, email messages were sent via a mainframe computer, and recipients would receive a printout of the message. To send a message to multiple recipients, the sender would have to create multiple printouts and send them individually.

The introduction of the Cc field in email clients made it much easier to send a single message to multiple recipients. The first email clients to include a Cc field were Eudora and Pine, both of which were released in the 1980s. Since then, the Cc field has become a standard feature in most email clients.

How the Cc Field Works

When you send an email with recipients in the Cc field, all recipients will receive a copy of the email, but only the primary recipient will be able to see who else was included in the Cc field. This means that the Cc field is a way to send an email to additional recipients without them being the primary recipient or the only recipient who can see the message.

For example, if you send an email to your boss with a colleague in the Cc field, your boss will receive the email as the primary recipient, and your colleague will receive a copy of the email as a Cc recipient. Your colleague will be able to see that the email was sent to your boss, but your boss won’t be able to see that your colleague was included in the Cc field.

Best Practices for Using the Cc Field

Now that we know what the Cc field is and how it works, let’s talk about best practices for using it.

Use the Cc field sparingly

Only include recipients in the Cc field if they need to be kept in the loop but aren’t the primary recipient of the message. If the email is intended for multiple recipients, consider using the “To” field instead.

Be mindful of privacy

Only include recipients in the Cc field if you have their permission to do so. Be mindful of including sensitive information in the Cc field, as it can be seen by anyone who receives a copy of the email.

Use the Bcc field for large email lists

If you’re sending an email to a large group of people who don’t need to see each other’s email addresses, consider using the Bcc (blind carbon copy) field instead of the Cc field. This will hide the recipients’ email addresses from each other.

Don’t use the Cc field to cover your bases

Including someone in the Cc field doesn’t mean you’ve communicated with them. If you need to communicate with someone directly, use the “To” field instead.

Double-check before hitting send

Before you hit send, double-check the recipients in the “To” and “Cc” fields to make sure you’re sending the email to the right people.


The Cc field is a useful tool for sending copies of an email to additional recipients without them being the primary recipient. However, it’s important to use it wisely and follow best practices to ensure privacy and effective communication. By using the C
