Decide whether you have any stylistic constraints because of how the newsletter will be sent. If you are writing an e-mail newsletter, for instance, you'll want to make certain choices you would not make for a paper newsletter. An e-mail newsletter needs to feature enticing links and graphics in the body of the e-mail that will convince the reader to peruse the whole publication. A paper newsletter, on the other hand, would rely more on font sizes and the strategic placement of columns on the cover pages.
Consider your purpose. Decide whether you want your newsletter to encourage new customers to try your business, remind the community about your organization, give information about your organization's growth, share helpful information about your industry or another goal.
Choose a style that will best fit your organization type. For instance, a Fortune 500 business would likely choose a formal and business-oriented style that presents straight facts with lots of data. If you are operating a non-profit that deals with saving animals or giving money to the homeless, however, you might choose a softer, more conversational tone, describing the success of your organization in vignettes.
Consider your audience as you chose your writing style and format. Offer information that will entice your audience and convince them to keep reading. For instance, in a newsletter for teachers, Newsletter Writing Tips suggests a list of web sites for teachers, an advice column, a teacher's news section, and a special section for each grade level. If your newsletter has a more formal, business style, consider that your audience, business people, is short on time. In this case, you may want to use many charts or graphs instead of words to get ideas across.
Incorporate graphics and formatting that enhances your chosen style. Choose traditional fonts, neutral colors and professional stock photography for a formal, business newsletter. If your newsletter is more casual and conversational, advertising a daycare business or a pet store, choose graphics that look childish, bright and fun, like children's artwork and comic fonts.
