Email Payslips - Change default email text?

SOLVED

I can generate electronic payslips that get pushed to outlook ready to send just fine but where can I alter the default text that appears in the email itself? 

At present its just a generic notice about the report being generated as a pdf and download a suitable viewer. 

I want to alter this to be more relevant to our company with information regarding the payslips.  I certainly don't want to have to copy and paste the same email text into 57 emails every month. 

Can someone please point me in the right direction.

Thanks
