Wordpress Plugin needed

Is there a plugin/tool, where you can put a button on a page, and if the user click it, he get's mailed an mail with a file, or a 96h download link?

Check out wp plugin MAXBUTTONS (free and pro). But there would be one problem: how knows the button to whom it should send the mail. Maybe you try newsletter or contact forms and configure them a bit.
