The Details are important _ Pay special attention to the details. They affect your readers very much. Details like alignment of the texts and the number of lines which your paragraphs include, can make readers bored or can interest them. Try not to make your paragraphs longer than 3 or 4 lines. When your paragraphs are short, people will read them easily. But if they are long, it will seem overwhelming to people. The colors you use in your newsletter design is important as well. So you should know a little about colors psychology. It's not hard. You must already know about the effect of every color on people, before designing or choosing your newsletter template.
The other design factor aside from the text is the imagery that you can use. Many of the newsletter templates will come equipped with basic clip art or graphics. Others will include areas where you can paste in your own graphs, photographs, or other graphic items that help round out the information. It's important to remember that the first thing that people often look at, even before the headlines, are the images, so make sure that they are strong ones that are eye_catching. Color newsletters also tend to be more appealing than those in black and white, though they can cost a bit more to print.
