I just copy (or type) whatever text I need in a macro in WORD and I can use that for my emails as well. I don't know how 2007 is set-up for working with macros but earlier versions work just fine.
Once you have one macro created, copying and pasting to create variations is a snap. If you prefer you can (of course) set up your own button on the toolbar that will contain these macros for email (or letter) use.
