If approval is required (makes sense) then I'm unlikely to get it.
The recipient is my wife. She receives about 50 emails a day, and gets around to reading at least 2-3 of them.
She's in the state where 99% of her incoming emails have vanished off the bottom of the area of her inbox that she reaches.
She refuses to setup filters, or folders/labels to categorise her email.
This is where scruples come into play. My fingerprint can unlock her tablet, so I could just go in there and setup the approval. We have reciprocal access to our tablets, as we'll need it when one of us goes west.
