    add_filter( 'wp_mail_from_name', array( $this, 'get_from_name' ) );
    add_filter( 'wp_mail_content_type', array( $this, 'get_content_type' ) );

    $message = apply_filters( 'woocommerce_mail_content', $this->style_inline( $message ) );
    $return  = wp_mail( $to, $subject, $message, $headers, $attachments );

    remove_filter( 'wp_mail_from', array( $this, 'get_from_address' ) );
