Why Many People Still Don’t Know What BCC in Emails Is—And Why It Matters

Reviewed by: Liam Chen

Despite the fact that emails are one of the most commonly used forms of communication in both professional and personal settings, many people are still unaware of some of its fundamental features—one of the most important being BCC (Blind Carbon Copy). While features like “To” and “CC” (Carbon Copy) are often well-understood, BCC remains a mystery to a surprisingly large number of users. So, just how many people don’t know what BCC is, and why does this matter?

In this article, we’ll explore the reasons why BCC is underutilized, the implications of not using it properly, and what can be done to improve email literacy.

What is BCC in Emails?

Before diving into the statistics and implications, let’s first clarify what BCC is.

BCC, or Blind Carbon Copy, is an email feature that allows you to send a message to multiple recipients without revealing their identities to each other. Unlike the CC (Carbon Copy) field, where all recipients can see who else received the email, BCC keeps this information private. It’s particularly useful for protecting privacy, avoiding reply-all chains, or sending mass communications where the individual recipients don’t need to know who else received the message.

Despite its simplicity, BCC is often misunderstood or ignored by many users.

How Many People Don’t Know What BCC Is?

While there isn’t a definitive study specifically quantifying how many people don’t know what BCC is, broader email literacy surveys offer insights into the general understanding of email features.

A Pew Research Center study from 2019 found that a large portion of users only utilize basic email functions like sending, replying, and forwarding messages. More advanced features such as filters, rules, and BCC were far less frequently used, suggesting a significant knowledge gap when it comes to email etiquette and privacy tools.

Here are some relevant points to consider:

Digital Literacy: Research shows that up to 30% of email users may not be familiar with advanced email features, including BCC. This is particularly prevalent among users who are self-taught or use email for basic communication purposes without ever having formal email training.
Generational Differences: While younger generations, such as millennials and Gen Z, are more tech-savvy overall, many are unfamiliar with older terms like “carbon copy” and its digital derivatives like CC and BCC. For them, these terms don’t resonate the same way they might for older generations who have a historical understanding of carbon copies in the context of typewritten documents.
Business Users vs. Casual Users: Professionals in corporate environments are far more likely to use BCC regularly due to the nature of mass communication and privacy concerns. In contrast, casual users—those who use email primarily for personal communication—may never encounter a scenario where BCC seems necessary, leading to low adoption and awareness rates.

Why the Lack of BCC Awareness Matters

Understanding BCC and when to use it is critical, especially in situations where privacy and professional etiquette are at stake. Failure to use BCC properly can have several consequences:

1. Privacy Risks

One of the main purposes of BCC is to protect the privacy of email recipients. When sending an email to multiple people, especially in the context of a business, mailing list, or group message, CC-ing all recipients means their email addresses are visible to everyone else. This not only exposes them to potential privacy risks, such as unwanted contact, but also violates data protection regulations like GDPR (General Data Protection Regulation) in certain circumstances.

Example: A company sending out a mass promotional email with hundreds of customer email addresses visible in the CC field could inadvertently expose sensitive information, resulting in a breach of data protection laws and harming the company’s reputation.

2. Unintended Reply-All Chains

Another important function of BCC is to avoid the dreaded “reply-all” scenario. Without BCC, recipients can accidentally (or intentionally) respond to all individuals included in the email thread, leading to email clutter, confusion, and unnecessary communication chains.

Example: In a professional setting, a manager may send an email to a large group of employees. If the recipients are all in the CC field, a single reply-all could flood everyone’s inboxes with responses that are only relevant to a few.

3. Professional Etiquette

In many professional settings, not using BCC can be seen as a breach of etiquette, especially when sending communications to external contacts. It’s important to be mindful of how emails are structured, especially when contacting clients, vendors, or large distribution lists.

Why People Don’t Use BCC More Often

There are several reasons why BCC remains an underutilized feature, despite its importance:

1. Lack of Awareness

As mentioned earlier, many email users simply don’t know what BCC is or how to use it. Since it is not immediately obvious to new users, those who haven’t been explicitly taught about its function might never use it at all.

2. Misunderstanding of Function

Even among users who are aware of BCC, there is sometimes confusion about how it works. Some mistakenly believe it functions similarly to CC, or they aren’t sure what happens when they use it. The lack of clear explanations from popular email clients doesn’t help this situation.

3. Overlooked Feature

Most people use email for straightforward tasks like sending individual messages or replying to conversations. Since BCC is generally considered an advanced feature, it’s often overlooked by casual users who don’t think they need it.

Improving Email Literacy and BCC Usage

Improving email literacy is key to ensuring that users fully understand all the tools available to them—especially in today’s world where privacy and security are paramount.

1. Educating Users

One of the most effective ways to improve the use of BCC is through education. Organizations and schools can incorporate email etiquette training into their onboarding processes or digital literacy programs. Email service providers can also play a role by making their features more accessible through tips, tutorials, or built-in guidance.

2. Promoting Responsible Use

It’s also important for individuals and companies to actively promote responsible email use by encouraging the use of BCC in appropriate situations. For example, when sending mass emails, a clear explanation of why BCC is used (to protect privacy) can help recipients understand its importance.

3. Making BCC More Visible

Finally, email providers could make the BCC field more prominent and accessible. For many services, BCC is hidden behind a drop-down menu or additional click, which reduces its visibility. By making BCC more prominent, users are more likely to consider using it.

Conclusion

Despite the prevalence of email in daily communication, a significant number of users are unaware of the BCC feature and its importance in protecting privacy and preventing unintended reply-all chains. Whether due to a lack of education, unfamiliarity with email best practices, or simply overlooking the option, BCC is underused by casual and business users alike.

As digital communication continues to evolve, improving email literacy—especially around advanced features like BCC—is critical. By understanding when and how to use BCC, individuals and businesses can protect the privacy of recipients, avoid embarrassing communication mistakes, and adhere to professional etiquette.
