The method includes storing, in a digital letters database, a first digital letter created by an author who is a subscriber to the digital letters system. The method includes communicating an image of the first digital letter to a recipient subscriber device while the first digital letter itself remains as a single copy in the digital letters database. The image of the first digital letter is communicated in response to the author subscriber selecting to send the first digital letter to the recipient subscriber, and the recipient subscriber selecting to view the first digital letter stored on the digital letters database.
