Final answer:
End-to-end encryption means that personal messages are secured in a way that only the sender and receiver can access their content. This prevents unauthorized parties, including the service provider, from reading the messages. Regular email services without encryption do not offer the same level of message privacy and security.
Step-by-step explanation:
When your personal messages are end-to-end encrypted, it means that they are converted into a secure code that can only be deciphered by the sender and the recipient. No one else, not even the service provider itself, can read the contents of the message. This end-to-end encryption ensures that your communication remains private and is protected from hackers and any unauthorized third parties that may attempt to intercept the messages.
Unlike professional email platforms, where security protocols are often robust, regular email services don't typically provide the same level of encryption. It's important to note that what we consider as private email isn't entirely secure; once you send an email, there are many ways it might be accessed or shared without your consent. End-to-end encryption is designed to address this vulnerability by securing messages throughout their entire journey from sender to receiver.
