Wouldn't be cool to receive an email from yourself years after you wrote it.

Future.org lets you send a private or public (anonymous) mail to yourself, you simply have to give your mail id, write whatever you wish to, set a date and days, weeks or years later you will receive an email about which you would have most likely forgotten about. As the founders of this site put it "memories are less accurate than emails."

But why would they give you an option to send a public 'anonymous' email?

That is because, apart from letting people read what you wrote by including it in their public letters section, Future Me has published a book called "Dear Future Me" where they have compiled the best public yet anonymous letters.
