how to change Font of mail content

Dear Abapers,

I am having a requirement in which i have to send smartform as an attached PDF through e-mail. I have done that successfully, but the client also want the content of the mail to be of specific font.

The mail is having two things

1. PDF File - Which has been successfully implemented.

2. Some Content in the Mail body in a specific Font(Verdana), I am able to send the content also but dont know how to change the font.

I am using the following function module to send the email:-

FUNCTION 'SO_DOCUMENT_SEND_API1'

Now please tell me is it possible that we can have mail content be font specific? If so, how?

Thanks and regards
