Unsubscribe and Permission

摘要

Seth Godin wrote "Permission Marketing" in 1999. Ten years later, most media companies don't understand the concept still. As Seth explains in the book and in his blog numerous times, when I give you my e-mail address, it is a trust issue. I trust that you will not spam me; inundate me with off-topic e-mail; and most importantly not sell my e-mail address to third parties, even if they are your partners.
