The main point of final formatting is to make sure your newsletter will appear correctly on your subscribers machines. We have already covered how links should be constructed for AOL customers, but an even more important issue is text wrapping. Whenever you send or receive an e-mail the text is usually wrapped. This means that if a line has 300 characters on it, it is broken up in several lines of a certain length so you can read it without having to scroll width ways. With your newsletter it is different.
Most people fix the word wrapping in their newsletters manually.
Alternatively you could use a program such as Textpad, or even Outlook Express if you don't mind cutting and pasting your newsletter a bit. Word wrapping is not difficult however, and is best demonstrated by example. Imagine this is a paragraph in your newsletter. It is not wrapped by default and the computer just wraps it whenever it sees fit so that it will fit into an HTML table or into the viewing area in your e-mail program. As such, it could look messy if people have different wrapping settings.
