Especially useful for outdoor sales people who arent necessarily in front of a computer all day, just a real quick summary email that goes out to list out all of the tasks on that day without having to log into the system on a phone / tablet [e.g. tiny screen] to work out who you were supposed to be following up that day!
This would make it so much easier for everyone to have a quick snapshot of their day without having to open PS and click on the notification. Also if another member of staff us unexpectedly off on a certain day then it would be really easy to check through the email to see if anyone is urgent for a call or whether it can wait until their return :)
