I don't receive an email when a comment is posted

Hi,

I have configured this plugin in my website and users of it can leave comments with it. But I don’t receive emails when it happens, so I’m not aware that they are leaving comments until I check on the pages or posts.

The default behavior for this on facebook is that you get an email so you can notice the message.

My website is http://luiseduardovivero.com/

Am I missing something in the configuration?

Thanks and regards,
Luis.
