As you develop, you can increase the frequency if it is necessary. Each issue needs to contain basic information such as links back to your site, how to unsubscribe, and a recommendation that the subscriber forward the issue to their friends and colleagues. Subject to the aims of your list, you can also include guest articles provided that they provide useful information to your subscribers. A key measure of your list performance is the levels of unsubscribe requests. This statistic is a strong indicator of how well you are doing.
People unsubscribe for a variety of reasons.
However, high levels of unsubscribe requests can indicate that you are failing to provide the content that the subscriber was expecting or that you are inadequately targeting the acquisition of new subscribers. Try to find out the reasons people unsubscribe if the level is of concern to you. Then act on the information you have discovered so you can improve your ezine and retain the people still on your list. List Promotion Resources Don t solely rely on your web site to generate new subscribers for your opt-in list. Register your list in the search engines, ezine directories, and ezine announcement lists.
