Rapture Letters is a site that promises to send an e-mail from you to the names you specify, after the Rapture happens and you have presumably left the planet.
Note that these letters go out on the first Friday after the Rapture. Your designates will receive another letter every Friday after that.
This may come as a shock to you, but the one who sent you this has been taken up to heaven.
(What poor sysadmin is going to be stuck behind running this operation?)
