We'll explore the reasons behind this and share guidance from the Information Commissioner's office (ICO) on how to send bulk communications safely.

In this episode I want to explain the importance of understanding the difference between CC (carbon copy) and BCC (blind carbon copy) in email communications.
Despite the technological advancements of the modern era, email remains a widely used and vulnerable platform for cyberattacks.
Data breaches often result from improper use of CC, posing significant risks to businesses and individuals alike.
The Information Commissioner's Office (ICO) has published guidance on this issue, emphasising the need for organizations to adopt appropriate security measures when sending bulk emails.
The Consequences of Misusing CCThe ICO has observed a disturbing trend of data breaches caused by incorrect usage of CC.
These breaches have the potential to cause real harm, especially when sensitive personal information is involved.
NHS Highland, an NHS organization, was reprimanded after inadvertently exposing the email addresses of individuals accessing HIV services due to a CC error.
The ICO's response highlights the severity of such breaches, as this incident could have resulted in a significant fine if it had occurred in the private sector.
Protecting Personal InformationEven if an email does not contain sensitive content, the mere knowledge of who received the email can inadvertently disclose confidential information.
It is crucial for organisations to assess and implement appropriate technical and organisational security measures when sending bulk emails.
Training staff on security protocols is also essential to reduce the risk of data breaches. Considering alternative secure methods, such as bulk email services or mail merge, can help prevent accidental disclosure of personal information.
