Decide the goal of the newsletter. Newsletters are generally used to keep members of a group up-to-date with news. Organize your thoughts and decide what you want to say.
Open your newsletter software. The best option is to use Microsoft Publisher, which would have come with your Microsoft Office software. If you don't have Microsoft Publisher, Scribus is a good alternative.
Choose a template you like. A template will have been designed to have the look of the newsletter, making it so that all you need to do is type in the information you want.
Type in your information. Templates will have dialogue boxes for you to type in your information. Simply click on a box and type.
