wpcf7_before_send_mail not being called?

function wpcf7_addto_newsletter (&$WPCF7_ContactForm) {
/* Use WPCF7_Submission object's get_posted_data() method to get it. */
$submission = WPCF7_Submission::get_instance();

if ( $submission ) {
    $posted_data = $submission->get_posted_data();
   $id = $posted_data->id;
   $title = $posted_data->title;
   }
   wp_mail( '[email protected]', 'title'.$id.' '.$title, 'The message' );
}

function wpcf7_init_before() {
  add_action("wpcf7_before_send_mail", "wpcf7_addto_newsletter");
}
add_action("init", "wpcf7_init_before");

I have written the code above and if I add a wp_message into the init function it’s being sent, but the one in the addto_newsletter is never sent.

I have WordPress 4 with 4.0.1 of the plugin, the forms are being emailed correctly, and if I introduce a syntax error it is picked up, it just appears the function is not being run?

Please can any one spot what I have done wrong.

Thanks
