I've updated my email in the "General options" and "Contact us section," but I never receive any email despite seeing the success prompt.
I am operating out of child theme, and have edited the front-page.php as shownhere.
From what I can tell there's nothing wrong with the code preventing the email from going through.
This is what I believe to be the only relevant code: http://pastebin.com/Z3knQtG5
