Add to tour pluggin

Hi !

Is there any plugin that allows to add check boxes (or “Add to cart / tour” button) in front of or after some paragraphs (not all of them indented the same, nor on the same page) which readers can check / click and later email me those checked paragraphs (or only their titles) like “Add to cart” buttons do (but without compulsory extra information such as prices) ?

Thank you very much !
