Provide content in the email body

Reports and Notifications emailed to clients allow us to communicate to a larger audience (who are not regular users of the system: C-level execs). It is critical that these contain some text that can be used to identify the dealer/solution provider. Further, facility for variable/custom text could be used to
make offers, etc. to specific customers (20% off xyz for next 10 days)

So, it would be great if we could be able to provide some standard content in the body of email in the near future.
