CC and BCC in Emails: Purpose, Difference, and Deliverability

Estimated reading time: 6 minutes

Understanding email etiquette and tools like CC (Carbon Copy) and BCC (Blind Carbon Copy) is crucial. These two options are vital in managing recipients, ensuring privacy, and keeping your communication professional. Whether you send updates to your team, share newsletters, or coordinate with stakeholders, knowing the difference between CC and BCC can significantly improve your email effectiveness.

What is CC in Email?

CC stands for “Carbon Copy”. The term comes from the old practice of using carbon paper to create a copy of a document. In emails, the CC field allows you to send a copy of the email to recipients who need to see the message but are not the main recipients.

Purpose of CC in Email:

• Visibility: All recipients included in the CC field can see who else received the email.
• Informational Purposes: CC keeps others in the loop without requiring direct action.
• Transparency: Helps ensure everyone involved is aware of the communication chain.

When to Use CC:

• To update team members who don’t need to take action but should be informed anyway.
• To include stakeholders who should be aware of the conversation that is taking place.
• To maintain transparency with all parties included.

Example of CC in an Email:

Imagine you’re sending a report to your manager, and you want to keep your team leader informed.

• To: manager@example.com
• CC: teamleader@example.com
• Subject: Project Update

Both recipients can see that the email was sent to the manager and CC’d to the team leader.

What is BCC in Email?

BCC stands for “Blind Carbon Copy”. This option allows you to send an email to multiple recipients without revealing their email addresses to others. Unlike CC, the BCC field ensures confidentiality.

Purpose of BCC in Email:

• Privacy: Recipients included in the BCC field cannot see each other’s email addresses.
• Mass Communication: Ideal for sending bulk emails, such as newsletters or announcements.
• Discretion: Prevents unintended reply-all messages and keeps communication professional.

When to Use BCC:

• To send emails to large groups without exposing email addresses.
• To ensure confidentiality when sending sensitive information.
• To avoid overwhelming recipients with reply-all responses.

Example of BCC in an Email:

Imagine you’re sending a newsletter to 50 clients:

• To: yourname@example.com (you can put your own email here)
• BCC: client1@example.com, client2@example.com, client3@example.com
• Subject: Monthly Newsletter

In this example, all clients will receive the email, but none of them can see the other recipients.

What is the Difference Between CC and BCC?

CC vs BCC breakdown:

Feature	CC (Carbon Copy)	BCC (Blind Carbon Copy)
Visibility	All recipients can see who is CC’d	Recipients cannot see who is BCC’d
Privacy	Email addresses are visible	Email addresses are hidden
Purpose	Transparency and collaboration	Privacy
Reply-All Impact	Allows reply-all to all recipients	Reply-all does not include BCC’d users
Use Case	Keeping coworkers informed	Sending emails to large or private groups

Common Mistakes to Avoid with CC and BCC

1. Overusing CC: Including Too Many People Who Don’t Need the Information.

Adding too many people to the CC field can quickly turn a simple email into an overwhelming and confusing communication chain. When unnecessary recipients are included:

• Information Overload
• Inbox Clutter: Overuse of CC can cause important emails to get lost in a sea of unnecessary notifications.
• Confusion About Responsibility: If multiple recipients are CC’d, it can become unclear who needs to act on the email.

2. Ignoring BCC in Group Emails: Exposing Recipient Email Addresses.

When sending emails to multiple recipients failing to use the BCC field can expose everyone’s email addresses. This is unprofessional and can have serious consequences:

• Privacy Breach: Recipients may not appreciate their email addresses being shared without consent.
• Spam Risks: Exposed email addresses can be misused or targeted by spammers.
• Loss of Trust: Clients, customers, or colleagues may lose confidence in you.

3. Sending “Reply-All” Responses to CC’d Recipients.

Another common mistake involves replying to all recipients in a CC’d email chain when unnecessary. This often results in:

• Unwanted Notifications: Recipients may receive irrelevant follow-up emails, cluttering their inboxes.
• Wasted Time: People read emails that don’t apply to them.

How CC Affects Email Deliverability

The CC field sends a copy of the email to visible recipients. While this works well for collaboration and transparency, overusing CC can negatively affect deliverability.

Higher Risk of Triggering Spam Filters

Spam filters may flag the email as “bulk email” if too many people are copied. Moreover, including unfamiliar email addresses can result in recipient complaints or bounced emails, damaging your sender reputation.

Impact on Engagement

Email deliverability is often influenced by recipient engagement, such as opens and replies. Some recipients may ignore the email because it feels impersonal. Low engagement signals (low opens and no replies) can harm your domain reputation over time. You can use GlockApps to test your email deliverability!

How BCC Affects Email Deliverability

The BCC field is designed to send emails discreetly without revealing recipient details. While this is useful for privacy and bulk emails, it can create deliverability challenges if misused.

Bulk Email Risks

ESPs view emails with many BCC recipients as potential bulk mail, triggering spam filters. Also, invalid email addresses in the BCC list can cause bounces, damaging your sender reputation.

Seed Lists and BCC

When using BCC to send emails to large groups, it’s important to ensure inbox placement to avoid triggering spam filters. A seed list — a set of test email addresses across different email providers — allows you to monitor where your emails land (inbox, spam, or junk) before sending them to actual recipients. Misusing BCC, such as including too many recipients or failing to personalize content, can harm deliverability. By testing your emails with tools like GlockApps, you can identify issues, optimize your sending practices, and ensure your BCC emails land in the inbox. 

Conclusion: Balancing CC, BCC, and Email Deliverability

Both CC and BCC are useful tools in email communication, but misusing them can harm your email deliverability. Do not overload recipients in the CC field or send bulk emails through BCC, so you don’t increase the risk of spam flags, bounces, and low engagement.

To maintain high deliverability:

• Use CC for small, relevant groups.
• Reserve BCC for privacy-conscious communications, but avoid using it for bulk emails.

By following these best practices, you can ensure your emails reach the inbox, build trust with recipients, and maintain a strong sender reputation. Remember to use the best email deliverability tools like GlockApps!
