With an electronic mailing list, you’ll be able to send one and the same email to separate recipients at the same time. The list is a collection of their email addresses, so if you send out one single email to the list’s email address, firstname.lastname@example.org – for instance, it’ll be re-sent automatically to all the subscribers immediately. Normally, people have to register for such a mailing list, but sometimes e-mail addresses can be added manually as well, based on the application that is being used to administer the mailing list itself. You can use the mailing list feature to contact prospective or existing clients and to send them announcements, new offers and other types of info on a periodic basis. This will prove your commitment to keep in touch with them and will increase the reputation of your web site.
