With a mailing list, you’ll be able to send the exact same email message to different users at the same time. The list is a collection of their email addresses, so if you send out a single message to the mailing list’s email address, firstname.lastname@example.org – for example, it’ll be re-sent automatically to all the mailing list subscribers instantly. Normally, people have to sign up for such a list, but sometimes their email addresses can be included manually as well, based on the software program that is used to administer the mailing list itself. You can use the mailing list feature to touch base with prospective or current customers and to send them announcements, brand new offerings and other sorts of info on a periodic basis. This will show your desire to stay in touch with them and will enhance the reputation of your web site.
