Newletters signup not working

I am using two newsletter sign up widgets. One is in the right column and the other is in the right section of the footer. You can see them in action at http://www.couponbum.com.

I do not know if I am using them correctly. When I input a test email address the form on the right column of the page looks like it is working since it says a confirmation email has been sent (see screenshot). However, I do not receive any email indicating someone has signed up for my site’s newsletter. Perhaps, I do not have the form coded correctly to use the widget.

As for the newsletter widget in the right footer area, it does not appear to be working at all. Not sure how to fix the functionality of this widget. Please help me fix these issues.
