JDEdwards Orchestration Email Message - Font Apply

Hi all
I was trying to develop a Restful DataRequest to Email Service using JDE Orchestration. I was able to get an email when I run my Orchestration with all required data. I want to apply the font to email message I received. I have used Groovy Code to parse the data from DataRequest and sending to email Message component.I also tried to keep HTML tags <p> but, did not worked. The reason for applying font is for proper alignment look.
Could anyone help with suggestion would help me enough.
