What is the Difference Between CC and BCC?

Today, when asking what BCC in email is, we can think of it as a way to send a single message to multiple contacts—giving you a purely electronic way of copying your emails. However, where BCC differs from standard CC is that, whenever you enter email addresses into the BCC field, those email addresses will not be shared with the recipients of your email.

The “blind” part of BCC essentially hides any email addresses you enter into that field from the contacts you send your message to.

But what are CC and BCC in email? The early days of email were based on letter writing (electronic mail), and in the same way, you would produce two copies of a letter using carbon paper, you could now send an email to two people using the CC protocol. Put simply, by using the CC field within your email, you can easily send copies of your email to multiple email addresses.

The BCC field is, in essence, an enhanced version of CC and fulfils its specific purpose.

This function is designed to ensure you don’t share personal email addresses when sending email newsletters or other blanket emails to numerous contacts.


The meaning of CC and BCC is straightforward, and both terms reference an old method used to duplicate documents. Here’s what CC and BCC stand for:


CC ➡️ Carbon Copy

BCC ➡️ Blind Carbon Copy


Before the development of photocopiers, a sheet of carbon paper was used between an original document and a blank sheet of paper. As the document was written or typed on, the carbon paper transferred the content onto the blank sheet of paper.


BCC can be traced all the way back to the invention of email itself and is one of the earliest features that we still recognize today. BCC is an extension of CC (Carbon Copy), taking its name from the practice of using carbon paper to transfer original letters onto separate sheets of paper—therefore creating a quick and simple copy. The blind part of BCC, however, is unique to email.

In most cases, all contacts will be familiar with each other or will be expecting an introduction from you.

  • Mass Emails — These can include marketing emails, brand updates, sales emails or any other type of message that is sent to multiple recipients who share no association with each other.
  • Introductions —Sometimes, it can be useful to use BCC in an email introduction that neither recipient has requested or is expecting. Using BCC, you can connect people without revealing their email addresses, making an initial introduction that either recipient can choose to either accept or reject.
  • External Emails — BCC can be useful when sending external emails to clients, customers, or even colleagues in other locations. If you need your boss to be part of the thread without revealing a specific email address, then BCC is what you need.

How Important is it to Use CC and BCC Correctly?

In many cases, using CC and BCC correctly is a matter of email etiquette and professionalism. However, there are occasions when using the incorrect protocol may have legal implications. Therefore, it is important to ensure you are familiar with the correct uses of both. Always remember that:

  • BCC must be used when sending out marketing emails, newsletters, or other unsolicited emails. If you share personal data (email addresses) in these cases, there may be legal implications.

  • BCC is not used when sharing sensitive information with superiors regarding the performance of coworkers, clients, partners, or anyone else. In a worst-case scenario, the person you are discussing (and who is part of the thread) could hit “reply all” and the secret nature of your message will be shared with all participants. This may also have legal implications.


CC and BCC — Do’s and Don’ts

There are a few things to remember when using CC and BCC. Here we look at the most important points to think about before hitting send on that all-important email:




Use CC when you need to ensure someone is kept in the loop. You can use CC as an FYI when you don’t necessarily need any further input from that person.

Use CC in a passive-aggressive way. If someone hasn’t replied to your email, then don’t CC the boss prematurely.

Use CC when you need to include more contacts in an email thread that is already running.

Use CC to micromanage projects or staff. Requiring the use of CC on ALL communications is stifling.

Use CC when introducing people who have requested an introduction. Doing this allows contact details to be shared without you necessarily remaining part of the conversation after the initial introduction.

Don’t use CC when you are introducing people who will be working on the same project as you. You will want to remain part of the conversation as you progress.

Use BCC when emailing individuals who want their privacy respected.

Don’t use BCC simply to sneak in a superior’s email as a method of “checking up” on someone.

Use BCC whenever sending out marketing or corporate emails to people from other companies.

Don’t use BCC when sending our marketing or corporate emails within your own company.
