Solution:
You aren’t even passing any variables to the function, so using wp_mail is useless because it has no information from the function to use.
You need to define the following: wp_mail($email,$titile,$text);
More specifically: $email,$titile,$text
inside your functions parameters: function wpwoopush_test($email,$titile,$text)
and as @Ben suggested, spell check on your variable names ($titile)
so you aren’t using an undefined variable in the function if you go to edit it later.
Hope this helps!
