Free Temp Mail Service is a tool that helps users create temporary email addresses that do not exist in their primary email accounts. The idea behind it is that some people can create spam mail addresses and use them to send out advertising material. It is especially useful for bloggers, journalists, and businesses that require some sort of temporary account to send messages to their clients.

The Free Temp Mail Service extension allows the user to easily generate temporary email addresses in the form of a random alphanumeric string. The user can then send any emails to this account and they will automatically expire after a certain amount of time.
