I recently read a blog post by Seth Godin Please don't kill the blogs, which is an "open letter" to Google where he expresses his frustration with the way Gmail has been putting his subscribers’ blog notifications in their "Promotions" tab instead of in the Inbox.

As an entrepreneur with a vested interested in email, not so long ago I’d argue with anyone that email marketing wasn’t a commodity. A recent conversation with an industry colleague changed my perspective. Looking at Merriam-Webster, a commodity is a ‘mass-produced unspecialized product’. By that definition, the sending of old-fashioned email blasts is clearly a commodity. Everybody can (and likely does) do it.
