Dead Man's Switch is an application that allows you to send emails to your loved ones from beyond the grave. Simply enter a few messages to people you select, Dead Man's Switch will periodically ask you if you are all right, and send them if you don't reply. DMS is one of the few projects of its kind, boasting thousands of users.
I'll concur.
