In apps where I want stuff to happen when a doc is updated/saved, I force the user to use a ‘save’ button that has all the code I want executed baked in. In that situation, you can build a from/to/subject/body any way you like. The methods to force users to hit your button to save are documented elsewhere in this forum (faq of faq or search for ‘prevent save’).
If you can live without the name in the subject line but have a dead-bang easy solution, check out Audit Manager at OpenNTF.org. It allows you to set up an audit trail that includes an email to <name/group you want> when a doc is saved.
