A self-destructing email is an email that is designed to disappear or become inaccessible after a certain period of time or after it has been read by the recipient. The goal of self-destructing emails is to provide an extra layer of security and privacy for the sender.Typically, a self-destructing email is sent using a specialized email service or application that offers this feature. The sender can set a timer for the email to self-destruct after a few days, hours, or immediately after the recipient has read it.The self-destruct feature can help to protect sensitive or confidential information in the email. It can also prevent the email from being forwarded, copied, or shared. However, self-destructing emails are not foolproof and can be screenshotted, and more tech-savvy users may be able to restore them, so they should not be considered a fool-proof solution for secure communication.
