According to a reliable dictionary, a newsletter is a bulletin issued periodically to the members of a society, business, or organization.
In this chapter, we will be building an e-mail newsletter, that allows members to subscribe and unsubscribe, receive updates on certain categories, and also allows a marketer to check how many people visited a certain link.
We'll be building an authentication system for our users to log in and log out of the newsletter management system, which is a social login system for subscribed members to easily check their subscriptions, and simple dashboards for subscribers and administrators.
