Email encryption is the act of protecting emails from being read by any other person except the intended recipient. It is used to protect privacy between the sender and the recipient. If the platform used to send email is clear without encryption, a malicious person can just open the email not intended for them. This is why email encryption software is vital to protect your privacy.
Email encryption software are programs that enable users to secure email and prevent them from being read by unintended parties while in transit. This software uses the public key to secure emails. Using a public key to encrypt email means that you send email published with a public key readable to others but you use your private key to open your email. Therefore the emails are in codes of unreadable formats while in motion to prevent hackers from accessing them. When they reach their destination the recipient uses the secret private key to decode the message. Essentially the email is locked up, then private key unlocks it at the destination and changes the codes into a readable format.
