I get very jealous of Seth Godin sometimes. He's like the Jerry Seinfield of marketers in that he makes obvious, observational statements but they are so true that it makes for great conversation. On his blog today, Big G has a simple statement to marketers sending out email: allow people to reply back to you or give them an address to send thoughts or comments into.
He writes, "I know it's horribly expensive and inconvenient to work your way
through the replies, but aren't the replies exactly what you need to
see? What an opportunity. Email is medium all onto itself. It's the only medium where the
human voice appears the same whether it's 'live' or 'recorded' and
where there's an expectation that all interactions are two-way."
Sometimes, it's easier to pretend everything's alright when in actuality, it's not. For the whole post (quick read), here you go.
