I really have let the amount of mail I receive every day that is just advertising material sneak up on me.
I made a decision a couple of weeks ago to unsubscribe from basically every one of these lists I very rarely read any of the messages and just delete them every time I receive them and I'm sick of my phone interrupting me during the day by pinging when it's just advertising material.
But there is so much of it. Years worth of accounts I have created on sites who now, in this economy, are sending marketing messages to me on time scales ranging from daily to weekly. Every day I have been unsubscribing to at least one 'newsletter' and it is usually higher than that.
Maybe I'm unusual, but having these types of marketing and even news messages mixed up with my real communication is annoying. Isn't this what RSS was created for? Why don't these companies provide RSS feeds for this information so people can keep their news items inside their news reader and allow them to keep there inboxes clear of clutter?
