If you are in a k2 override you probably can put a php echo in the override to create a mailto link and pick up the url and include it in the mailto link
<a href="mailto:
[email protected]?body=The message's first paragraph.%0A%0aSecond paragraph.%0A%0AThird Paragraph.">
break something like above up and add the link into the body and the links will be automagically added for you
