Send Link for Approval and Then Save Data in MVC

Question

I am creating a simple MVC application where Secreatry creates contact list for his boss. Contact list has simple fields FirstName LastName Phone no.

Catch

Secreatry cannot save contacList.
After submitting the contactList form , an email (containing link of contact) should go the boss and when Boss opens email he can approve or disapprove it.
When boss approves then only contact should be saved in Contact list

ProblemI am new to Asp.Net, i have Questions

1) when Secreatry fills the contactlist form and send to boss then where are the details saved ( i mean in which database??).

2) how to create am email link which after opening contains filled form + 2 new buttons Approve and Disapprove

I have no code to post i mean i want to understand how to achieve that
