For those with no background in desktop publishing software, the easiest way to make an attractive, professional-looking newsletter is to use a template. Simply download a template from a website such as iNewslettertemplates.com or Lucidpress.com, and enter your content into the appropriate sections of the template.
If you have some design background or learn new software easily, Adobe InDesign is a good program for designing newsletters and other publications. It allows more creative freedom than a template, since it allows you to choose your own background designs, photos and layout. This approach is recommended for people who have a good sense of what looks good and a general understanding of which fonts, photos, colors and design elements tend to go well together. However, planning a layout and selecting appropriate fonts and photos can be time-consuming and intimidating to some people, and a template shifts the focus to the text content of the newsletter rather than the look.
An important thing to remember when designing something for print is that a lower image resolution might look okay on the web, but it will look grainy in print. Design professionals recommend a resolution of at least 300 dots per inch, referred to as dpi, for graphics and photos.
