CC vs BCC: What’s the Difference?
Learn the difference between CC and BCC fields in email, when to use each, and how to avoid privacy mistakes.
CC and BCC Basics
Email clients include To, CC, and BCC fields to control who receives a message and how visible each recipient is to others. CC stands for “carbon copy” and is used when you want additional people to receive the message openly. Everyone listed in To and CC can see one another’s addresses.
BCC stands for “blind carbon copy.” Recipients placed in BCC receive the email but are hidden from other recipients. People in To and CC cannot see who was BCC’d, and BCC recipients cannot see each other either.
Privacy and Email Etiquette
Using CC when you should use BCC can leak entire mailing lists and expose addresses without consent. This is especially risky for customer announcements, school updates, and community groups. When sending to a large group whose members do not already know each other, use BCC and address the email to yourself or an alias in the To field.
Reserve CC for small groups where participants expect their addresses to be visible, such as internal work conversations. Clear use of To, CC, and BCC helps keep threads readable and protects recipients’ privacy.
How to Send Group Emails Safely
Before you hit Send on a large announcement, create a contact list or paste recipients into the BCC field, add yourself in To, and write a short line in the email body explaining why they are receiving the message. If you need personalization, use a mail merge or newsletter tool rather than CC/BCC to avoid mistakes.
Double-check attachments and links, then send a test message to yourself first so you can confirm formatting and that no addresses were exposed. This small rehearsal prevents embarrassing leaks and lets you catch typos before the real audience sees them.
