If you don’t want to give your real email when registering for a site, Guerrilla Mail offers a great hassle-free solution.
Often times, we just want to visit a site or join a forum discussion without having to sign up and register (and be prone to receiving spam later on). If this sounds like one of your concerns, then head on over to Guerrilla Mail, which is a free service that provides you with a disposable temporary e-mail address.
Upon visiting the page, you’re immediately assigned an email address, which at default lasts for one hour, although you may keep on extending its validity with the push of a button. You can also change the name of the email address if you want to.
Although this is a useful tool, it does have potential negative outcomes, such as using it to send hate mail or threatening messages. However, for those of you that don’t intend to commit any crimes, Guerrilla Mail, if used it wisely, can be an invaluable tool.
