I receive a number of newsletters for freelance writers. Most are the same. But the editor of one revealed she was an expert fisher-woman in an article she did on writing columns. Suddenly her newsletter took on much more life. And I rarely fish.
Life lives in the details.
Deliver detailed information General information doesn't work in ezines. Get very specific. If you're covering fly fishing in Montana, talk about individual rivers. Less is always more Make your newsletter short and it will be sweet to your readers. The best newsletters have two or three short items of 150 to 250 words, followed by some links to great sites.
