5 Reasons to Stop Using Cc in Your Emails, and How to Do Better Without Risk
You're organizing an online event. You send the invitation and the connection link to all participants... in the same email, using carbon copy. The famous Cc. Quick, simple, effective... or so it seems. But is it a good practice? Short answer: no. Here's why using Cc can be problematic, and most importantly, what alternatives to adopt to protect personal information, comply with Law 25, and improve your digital practices.
1. Cc Unnecessarily Exposes Recipients' Email Addresses
Carbon copy allows you to send the same email to multiple people, making all recipients' email addresses visible. That's where the problem lies. Each person receives not only your message but also the complete list of other participants. In other words, you're sharing email addresses without necessarily having been authorized to do so. And in a professional, community, or event context, this detail has very real consequences.
2. An Email Address Is Protected Personal Information
It's often forgotten, but an email address is considered personal information. The question to ask is simple: have the people in Cc authorized you to share their email address with others? In most cases, the answer is no.
When you use Cc, you communicate personal information to third parties without explicit consent. This constitutes unauthorized communication, which may violate personal information protection principles.
And since Law 25 came into effect in Quebec, this type of situation deserves your full attention.
3. Cc Can Lead to Non-Compliance with Law 25
Even without malicious intent, misuse of Cc can constitute unauthorized communication of personal information. Indeed, Law 25 imposes increased responsibility on organizations regarding the management and communication of personal information.
A simple poorly sent email can become:
- a privacy violation,
- a potential complaint,
- or an incident to report.
The problem is that this type of error is frequent, commonplace, and often unintentional. Yet its impacts can be very real, both for your organization and for the trust of your clients, partners, or participants.
4. Cc Errors Are Frequent and Hard to Fix
The good news is that there is a very simple solution: blind carbon copy (Bcc). Bcc allows you to send an email to multiple recipients without them being able to see the other people's addresses. Each address remains confidential, invisible, and protected. It's the equivalent of sending letters in individual envelopes, rather than displaying the full list of names on a public board.
For invitations, one-time newsletters, reminders, or group communications, Bcc should be your default reflex.
5. Cc Encourages Inefficient and Risky Digital Practices
Beyond compliance and confidentiality, there is another often forgotten issue: digital sobriety. Chain emails, "Reply All" responses, and long Cc discussions generate:
- more storage,
- more bandwidth,
- more energy consumption.
Limiting visible recipients, avoiding unnecessary replies, and structuring your communications also means reducing your digital footprint. Less data shared unnecessarily means more security, more efficiency... and a concrete gesture for the environment. And that's also what fraud prevention is about!
Best Practices to Adopt Right Now
Here are some simple habits to integrate into your organization:
- Use Bcc by default for group communications.
- Think before using "Reply All": is it really necessary?
- Centralize your mailings using appropriate tools (event platforms, newsletters, forms).
- Raise awareness among your teams: a seemingly harmless email can have significant consequences.
The majority of cybersecurity incidents and data leaks involve a human factor. It's often small habits, repeated daily, that open the door to problems.
Training to Prevent, Not Just Correct
Changing a habit as ingrained as using Cc requires more than a written instruction. It requires understanding the issues, risks, and best practices. Need help? We can help you with our cybersecurity training tailored to the specific needs of your organization. At CY-clic, we focus on a human, concrete, and accessible approach, because technology alone is not enough. It's the daily gestures that make the difference. A simple email may seem trivial. Yet, when used properly, it becomes a tool for protection, compliance, and trust.
