Permission - the great unknown in many Email circles

My latest iMediaConnection article is interesting, if only, because most big name marketers (client and agency side) are not familiar with permission levels or opt in marketing. Retailers use their catalog legacy strategy and decide they can email these folks if they have their personal info. This is dangerous.

An additional post on a theory that is very similar to mine can be found here on Email Marketing Reports. Mark Brownlow takes on assumed permission.
