Working from this generally outline, you can then break down the overall content into smaller articles that are easily digestible by readers. These can then fit into the various boxes and subheadings of the newsletter templates, for an attractive visual layout. It's recommended to break this information down into even smaller bits and pieces, including the use of bullet points and smaller boxes of facts and figures. Graphical information is helpful for business newsletters or the illustration of sales figures. These are just a few of the ways to show your message in an appealing way, which is helped along with the use of the templates.
This approach tends to work better for articles that are jam packed with information and/or those that take a broad, aerial view of the topic, but it can also work with articles that are a close up view of one specific topic. For example, I've written many articles on how to create an effective resource box, and from that one very laser beamed topic I have branched off articles on extremely specific elements of that already specific topic. I assure you, no matter what your article is about, you can write about it more in depth in a new article.
