spambox.us a service where you can create temporary e-mail address for specified life time and forward all incoming mails to regular e-mail address. When website’s ask for a e-mail address, you can specify the address created in spambox.us and not reveal your original mail id. And spambox.us mail address gets deleted after the specified life time and prevent your e-mail address from receiving spam mails.
This service is similar to the one already posted here. And the main difference between spambox.us and Guerrilla mail is that the latter does not ask for your e-mail address but the life span of the e-mail address is limited and cannot be specified by the user.
So which service do we go for and when?
I would prefer Guerrilla mail to try out some trial softwares and for one-off purpose. And prefer spambox.us for more general protection of your email address and for longer duration.
