Adding the below code to functions.php

I need to add the below code to the functions.php file. Where do I add it?

add_filter( 'haet_mail_use_template', 'disable_email_template_by_subject', 10, 2 );
function disable_email_template_by_subject( $use_template, $email ){
    if( stripos( $email['subject'], 'MY KEYWORD' ) !== false )
      $use_template = false;
  return $use_template;
}

Thanks
