Notification of Delivery to Admin/Staff

[Camoretro]

I am interested to find a way to either:

A) Get a notification when my customer's item is delivered 

or 

B) Get a notification exactly 3 business days after my product is delivered

Any solutions would be helpful! Thank you.

I'm think you can set up notifications like this with After Ship. I haven't used it in awhile but I remember it being pretty powerful, pretty sure you can do this.
