creating a mailing list using SQL Server as the database

I am tasked with creating an Email DL where managers can subscribe and unsubscribe at there convenience. In this type of a set up I am thinking that I will need a few tables.

Manager Table (first name, last name, email address)

dl1 (email address)
dl2 (email address)
dl3 (email address)
dl4 (email address)
dl5 (email address)

etc...

what I will like created is the manager will subscribe and the main manager table will house all the email addresses. During the subscription process the managers will then have the opportunity to decide on which DLs there will like to receive communications from (dl1, dl2, dl3, dl4, dl5, etc).

I have access to SQLServer 2014 and will be using it for this project. Any kind of help will be appreciated. I am hoping that one of you kind folks can start me going and I can add / modify the DLs as needed.
Thanks in advance for any help / assistance you can provide.
