Email communication has become part of daily life for many people. Whether receiving updates about a favorite product, reading an online newsletter or discussing new approaches to managing a health challenge, individuals, businesses and organizations communicate through email lists daily.
The benefit of email lists is that they can quickly and effectively distribute messages to a large number of people who have explicitly requested to receive the information, known as subscribers. The terms opt-in or permission-based email lists are used to refer to this type of communication.
