With an electronic mailing list, you will be able to send out one and the same email to different users simultaneously. The list is a collection of their email addresses, so if you send out one single email message to the mailing list’s email address, newsletter@domain.com – for instance, it will be redirected automatically to all the subscribers immediately. Normally, users need to subscribe to such a mailing list, but sometimes e-mail addresses can be included manually as well, depending on the software that is used to administer the list itself. You can use the feature to touch base with potential or current customers and to send them announcements, brand new offerings and other sorts of information on a regular basis. This will show your desire to keep in touch with them and will boost the popularity of your website.
