This is a simple idea I am going to assume ad networks are already doing, but if they aren’t, they should!

When you first get online at work in the morning some ad provider should note that this is the first time they’ve seen you in a few hours. The assumption should be that you must have just sat down at your desk so…

An alert should be sent to email marketers that they should send you their daily email now. This is email you’ve already signed up for, just the delivery time is now optimal since you were just “seen” online.
