Adding post content to email on button-click

I’ve used a simple button with a email function to send a particular article to someone. At the moment it looks something like this…

global $post;
        $title = htmlspecialchars($post->post_title);
        $subject = htmlspecialchars(get_bloginfo('name')).' : '.$title;
        $body = 'Kyk gerus na hierdie artikel: '.$title.'('.get_permalink($post->ID).').';

$email_article = '<a rel="nofollow" href="mailto:?subject='.rawurlencode($subject).'&body='.rawurlencode($body).'" title="'.$text.' : '.$title.'">'.$text;

I thought that using the_content() would add the post’s text automatically to the email. It didn’t work so I guess that since the title and the link can be transferred there must be some function that would also extract the contents into a email.

Is there something like that or is this even possible?

Thank you
