Ah yes it was probably web clips. However, note that this was placed at the bottom of the email thread, not the top. This help page states that web clips (including sponsored links) should only display at the top of the page: http://mail.google.com/support... "Web Clips show you news headlines, blog posts, RSS and Atom feeds, and relevant sponsored links, right at the top of your inbox." Unfortunately I didn't take a screenshot showing messages above.
