Why is email communication considered less secure than other forms of communication?

Email communication is considered less secure than other forms of communication primarily because it is often sent unencrypted between servers. This lack of encryption means that the content of emails can be intercepted and read by unauthorized individuals as they travel across the internet.

In many cases, the email is transmitted in plain text, making it vulnerable to potential threats such as hacking or eavesdropping. Without encryption, sensitive information contained in emails, such as personal data, financial details, or confidential business information, can be easily accessed by malicious actors.

Proper security measures, such as using encryption protocols (like SSL/TLS), can help enhance email security, but many communications still occur without these protections. This inherent risk in the way emails are handled is what makes email less secure compared to other communication methods, particularly those that automatically include robust security measures, such as certain messaging apps that use end-to-end encryption.
