Subscription Plugin

Hi, i have installed the subscribe by email plugin and I must have something wrong because it doesn't produce the results I expected.

The site I am working on all of the pages are basically static except for the pages created by the wpfuneralpress plugin when I add an obituary.

My desired outcome is to have an email sent to those who opt-in when a new obituary is listed. During my testing I don't get any emails when I add a post to that page. Any help would be appreciated.
