Don't be afraid to use images. They really liven up your letter. You can even embed slideshows (first build a gallery in the photo section) or videos directly into your newsletter as well.

If you left or right align the image, the text will wrap around the image automatically.

Another great thing about using the web is that you can get comments on your letter if you like. You'll notice below that there are threads (like comments) that people can start, or you could pre-post a thread in your discussion forum and ask for people to comment via a link you add to the thread.
