Changing content of E-mail based on project and task status cProject

Hi,

I am making some changes in cProject. In the 'Staffing' tab, once the resouce name is selected, there is a link 'Send E-Mail' which gets activated. Once 'Send E-mail' is clicked, a mail pops up in the outlook. I have to change the content of this mail based on different status of the project and task. Can anyone guide me as to how this is to be done. Is there any BADI available.

Regards
