With a mailing list, you are able to send out the same e-mail message to separate recipients simultaneously. The mailing list is a collection of their email addresses, so when you send out one single message to the list’s email address, email@example.com – for example, it will be forwarded automatically to all the mailing list subscribers instantaneously. Normally, people have to sign up for such a mailing list, but sometimes email addresses can be added manually as well, based on the program that is being used to manage the mailing list itself. You can use the mailing list option to contact potential or current customers and to send them newsletters, brand new offerings and other types of info on a periodic basis. This will demonstrate your commitment to stay in touch with them and will boost the reputation of your site.
