With an electronic mailing list, you can send out one and the same email to a number of users at the same time. The mailing list is a collection of their email addresses, so if you send out a single email to the list’s email address, [email protected] – for instance, it’ll be redirected automatically to all the mailing list subscribers straight away. Usually, users have to sign up for such a mailing list, but occasionally email addresses can be added manually as well, depending on the app that is being used to manage the mailing list. You can use the feature to reach potential or current clients and to send them newsletters, new offers and other kinds of information on a periodic basis. This will show your commitment to remain in touch with them and will enhance the reputation of your site.
