What is Email Encryption?

Email Encryption is a process that converts the content of an email from readable format to secret ciphertext. This ciphertext is understandable only to the intended parties, i.e., sender and receivers. So, when the sender sends an email to the receiver, during transmission it will be converted to ciphertext / algorithmic codes. Moreover, at the receiver end, it will be decrypted to the original format which the sender sent. However, all this encryption and decryption process is done at the back end. So, as an end-user, you don’t realize any major change. This process gives extra security to your email communication. It prevents unauthorized entities from spying on the communication process.

What is Password Protected Email?

Password protection feature protects your email by allowing it to open with the specific password set by the sender. While sending anything important or secret, the sender should protect the particular email conversation with a password. The sender usually sends passwords through some other channel of communication like SMS, calls, etc. This helps you to maintain secrecy for important financial, legal, and other documents and information.
