For years, the answer to that was easy: direct mail was good old, USPS delivered letters and postcards. These days, there isn't a single "one-size-fits-all" answer as to what exactly constitutes it. Truth be told, the definition of direct mail seems to change every day.
Now that it's no longer limited to the USPS, direct mail today can also be email, a text message, an instant message, a Facebook post, or any of a number of different kinds of social media communiques, from chat room interaction to a wiki entry.
