We know that with or without data content analysis of actual email
   messages, lots of information can be inferred through various forms of
   metadata collection. Given this reality the question becomes, what can
   be done?

   One strategy might be to consider the adoption of a time delayed email
   system. The reason why the use of such a mechanism to allow someone the
   ability to write an email, and then have it sent off at a specified (or
   randomly generated unspecified) date is useful for multiple reasons.

   If a program could be coded in a way which could delay the actual
   transmission of data in such a manner that the original time of
   creation was adequately masked, it could hamper nefarious metadata
   collection of time-stamping and possibly geo-locating of user
   information.

   For example:

   A person walks into a computer caf at 10am and sets an email to send at
   around 4am the following morning (via cloud or machine). The data gets
   sent at 4am when the building is empty. No CCTV photos/cameras are able
   to document who sent the message because the computer caf is unoccupied
   at 4am. The software is designed in such a fashion that it is nearly
   impossible to unmask the original time when the message was instructed
   to send, thus hiding the metadata associated with time-stamping, and
   thus hiding the true identity of the computer user at the caf at 10am
   the previous day.

   Any and all feed back regarding this idea is welcome.
