What is a key privacy concern related to email communication?

The primary privacy concern related to email communication stems from the fact that email is often sent unencrypted. When emails are transmitted without encryption, they can be intercepted and accessed by unauthorized parties, potentially exposing sensitive information. This lack of encryption means that anyone with the right tools or access to the network can read the contents of an email, making it risky to share confidential or personal information through standard email protocols.

While certain email services offer encryption options, it is not universally implemented across all platforms or accounts. Therefore, users must be aware that unless they specifically use encryption methods, their email communications may not be secure. This highlights the importance of using secure email practices, such as encrypting emails containing sensitive information and being vigilant about what is shared through email in general.
