What does BCC mean in an email?

3 Aug 2026

Learn what BCC means in email and its difference from CC.

Glossary

Blind Carbon Copy (BCC) is a feature in email that allows you to send a copy of the email to someone without the other recipients knowing. It is useful for sending emails to a large group of people without revealing everyone’s email address.

Ever sent an email to multiple people and accidentally exposed everyone’s addresses? That’s exactly what BCC prevents. BCC, or Blind Carbon Copy, lets you send emails to a group without revealing their addresses to each other.

In this article, you’ll learn what BCC means, why it matters, how it differs from CC, and practical tips to use it safely and effectively.

What is BCC in email?

BCC stands for Blind Carbon Copy. It hides the recipients’ email addresses when sending a message to multiple people. This keeps your mailing list confidential, protects privacy, and reduces the risk of your contacts being added to spam lists.

Half the Earth’s population uses email. So, there’s a lot for you to gain by using your webmail’s features properly. Now that you know what BCC means in email, you need to learn why you should use it and what might happen if you don’t.

Why BCC matters

Sending emails with BCC is not just a matter of etiquette—it’s about security, privacy, and convenience. Here’s how it helps:

1. Increases security

If hackers find an email address, they can try to discover its password, leading to people’s private information getting stolen. There’s no guarantee that this situation will happen, but it’s best not to risk it. Use BCC to keep people from discovering your client’s email addresses.

2. Ensures privacy

Even if these emails don’t get hacked, malicious individuals can subscribe to your newsletter, for example. If you don’t use BCC, they can collect all your email addresses and send them things like these below:

3. More convenient

BCC blocks the “reply all” option, which is paramount for your client’s convenience. Suppose you’re sending an email marketing campaign to thousands of people. Imagine if only 1% of them decide to “reply all.” BCC prevents these unwanted replies from reaching your clients.

4. Makes your message more personal

Many people may think that you sent an email directly to them instead of sending it to a group of people since BCC hides the other recipients. A personalised taste can go a long way in gaining your client’s trust. It’s even better if you use a tool that adds their name to the email’s greeting.

BCC vs CC: When to hide and when to show addresses

CC and BCC send an email to recipients. But CC recipients are visible to others, while BCC ones aren’t. Also, CC allows recipients to “reply all.” BCC doesn’t. Knowing when to use each is critical to email etiquette.

It’s best to use CC when you merely wish to notify someone that you’ve sent a message. For example, if you need to send an invoice, you can CC your boss so he knows you’ve done it.

Many email providers allow you to put several people in a message’s “To” list, but it’s better to use it only for the people who are the message’s target. If you only wish to notify someone else, like in the example above, leave those secondary recipients in the CC.

What does “always BCC myself” mean in email?

BCC yourself on emails you wish to follow up on later. After you send it, you’ll receive a copy. Since you’ve BCC’ed yourself, other people won’t know you’re also a recipient. This measure helps you keep track of important messages.

Conclusion

Using BCC correctly keeps your contacts safe, your emails professional, and your campaigns efficient. Start applying it today, and never risk exposing someone’s email again.
