Send link for approval and then save data

I am creating a simple MVC application where Secretary creates contact
list for his boss. Contact list has simple fields FirstName LastName Phone
no.
Catch
Secretary cannot save contactList.
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
Problem I am new to Asp.Net, i have Questions
1) when Secretary 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
