It's part of a month-long project called "Snail Mail My Email."
All you have to do is email a letter to a volunteer who handwrites it, adds a doodle on it, then slaps it into an envelope and mails it.
The project's creator says it's a way to make the world less "cold and impersonal".
Writers have already sent letters to the president... but say most of them are love letters.
The project ends in ten days.
