Laravel - Mail - Plain Text Emails

If you would like to define a plain-text version of your email, you may use the text method. Like the view method, the text method accepts a template name which will be used to render the contents of the email. You are free to define both an HTML and plain-text version of your message:

     * Build the message.
     * @return $this
    public function build()
        return $this->view('emails.orders.shipped')
