Graymail - just yesterday I finally unsubscribed from a product email that I subscribed to before the product was out. I glanced at, then ignored many emails, sales, holiday specials, etc. What made me do it? An email asking me how I liked the product. I don't have one, they should know I never bought one. If more companies would take the time to send meaningful emails or even unsubscribe me when they feel I'm not interested, I may sign up for more things. If they valued a quality list over the quantity my inbox would be a different place.
