How to add html into a body of an email using <a mailto:...?

Hi,

I wrote this:

<a href="mailto:?subject= this the subject&body=this is th body>send mail</a>

Code (markup):

However,I don’t to write flat text in the body. I want to add '<br/>' and an '<a>' tag in the body.
I tried:

<a href="mailto:?subject= this the subject&body=Hi <br/> this is th body <a href='blabla'>click here</a> ">send mail </a>

Code (markup):

But of corse it didn't work

Thanks.

 

Just a guess, but try converting the < and > to &lt; and &gt; in the body= parameter?
