This is not entirely accurate as viruses can be caused by several different file types, not only executables. Once a email is sent and then the attachment is opened a viri can then infect the host, an example is If I sent you a word document that contained macro viruses (not executable) it is a virus that only will attack other documents, such as text files, document files and spreadsheet files as well through the use of the macro program. The macro virus also may utilize other programs on your computer such as the Melissa virus in that when a user opens an infected document, the virus will attempt to e-mail a copy of this document to up to 50 other people, using Microsoft Outlook. This is not an executable it is done by opening a word document received through email. It only does the mass mailing once by checking registry keys. Other samples of what is thought to be viruses such are Happy99 Worm Program Promail.Trojan Hoaxes These are just as they state they are trojans, worms, and hoaxes similar to viruses but different. To get accurate information regarding these subjects you can research these at the Computer Incident Advisory web site hosted by the US Dept. of Energy at http://ciac.llnl.gov/ciac/CIACHoaxes.html there are several other sites that are resourceful as Jesse stated below, and also as Jesse stated below Email itself does not cause viruses only opening attachments in Email can in fact cause the start of a viri. Please note that email is not the only method that viri can be received as if you are a user that utilizes other services through networks (includes dialup) such as FTP, you can then receive viri as well.
