Bacn (pronounced like bacon), is email that has been subscribed to and is therefore not unsolicited, but is often not read by the recipient for a long period of time, if at all. Bacn has been described as "email you want but not right now."Bacn differs from spam in that the recipient has signed up to receive it. Bacn is also not necessarily sent in bulk. Some examples of common bacn messages are news alerts, periodic messages from e-merchants from whom one has made previous purchases, messages from social networking sites, and wiki watch lists.
