Internal newsletters are great tools to keep employees up-to-date on company news and events. However, the length of an internal newsletter should be determined based on the content and audience of the newsletter. Generally, a newsletter should be no longer than 1-2 pages. If the newsletter is predominantly informational and does not have any promotional or marketing elements, then a length of 2-4 pages is appropriate.
If the newsletter has promotional or marketing elements, then a length of 4-8 pages may be more appropriate. In either case, it is important to keep the content fresh and relevant to the audience.
