Does Drupal have this type of email optin module?

It's a bit like this:

What it does is create an horizontal email opt-in bar (for a free report or something like that) along the bottom of the page that stays on the page as the user scrolls up and down through the page (a bit like how facebook, G+ like buttons do along the side of webspages).

Any help would be greatly appreciated,
Thanks,
