Temp mail or temporary email is a service that allows users to create disposable email addresses. These email addresses can be used for a variety of purposes, such as signing up for online services or newsletters without revealing one's personal email address. Temp mail services typically delete emails after a certain period of time, usually within a few hours or days. This helps to protect users' privacy and prevent spam emails from cluttering up their inbox. Some temp mail services also offer additional features, such as the ability to create custom email addresses or to access emails via a mobile app.
