With an electronic mailing list, you’ll be able to send out the exact same email message to separate recipients simultaneously. The list is a collection of their email addresses, so if you send a single message to the mailing list address, newsletter@domain.com – for example, it’ll be re-sent automatically to all the mailing list subscribers instantaneously. Usually, people have to register for such a list, but sometimes e-mail addresses can be included manually as well, depending on the program that is used to administer the mailing list. You can use the mailing list option to reach prospective or existing customers and to send them newsletters, new offerings and other kinds of info on a periodic basis. This will prove your desire to remain in touch with them and will increase the popularity of your web site.
