How to change font size of e-mail body in following code

[ThrottleWorks]

Hi,

This is a non excel question.

I am using below mentioned code to prepare new e-mail from excel file.
I have taken this code form Ozgrid.

However I am not able to change the font size of entire e-mail body.

Also, the e-mail body starts from 2nd line of the e-mail (leave starting line as blank).
I tried checking it but could not find way to populate e-mail body from 1st line itself.

Can anyone please help me in this.
