Next, in order to properly maintain your list you will need a system that will help you to compile and properly manage subscriptions. If you're using a simple email program or address book, they can become bulky and cumbersome after a certain period of time. These scripts offer webmasters the ability to maintain their own mailing lists directly onsite. However, most Internet marketers are business owners and, if they're anything like me, they more than likely do not have the time to implement and manage their lists themselves. If this applies to you, a tool you will therefore need is what is called a mailing list server.
List servers are useful for discussions and particularly ezines.
Some web hosting companies offer list servers as part of their hosting packages while other sites provide the necessary scripts to configure your own list server. For starters, there are several elements that you must take into account when asking for your visitor's email address, especially on your web site. Mailing lists are not limited to email addresses that you've personally captured. They can certainly be leased or bought from a reputable, responsible, and ethical list broker. Unsolicited email uses a lot more resources and can be construed as an invasion of one's privacy.
