Knowing what to do when the company doesn t tell you anything is important. In general it makes sense to cover all the most likely bases. Make sure that you mention this in your e-mail, and give the company all the necessary information for viewing the files. If you also have your resume on the web as a .pdf file, then by all means include the URL in your post. It s important to make sure that the information is laid out clearly and logically.
Opinions vary on the importance of cover letters, but it won t hurt to include the information.
Group information logically and make sure that your headers are clear and descriptive. Use white space to group information. You did it with tabs, margins and paragraphs in the paper version. Now you need to use as many tools as you can to accomplish the same thing in the e-mail document. The person receiving the resume still has to read it.
