title: woocommerce add text to specific email
body: <p>I had asked this before but unfortunately I realized that the answer given did not work, so I am asking again:</p>
  
  <p>I am trying to add some text to the customer-order-processing email from <code>WooCommerce</code>, and it should ONLY be added in this particular email and ONLY if chosen payment method is <code>Paypal</code>. I have come so far as the text is added, and only when Paypal is chosen as payment method, but the text is displayed in every email to the customer now, for example also in the order-completed email or customer-note email. I have the following:</p>
  
  <pre><code>add_action('woocommerce_email_before_order_table','add_order_email_instructions', 0, 2);
              function add_order_email_instructions( $order, $sent_to_admin ) {
          if ( 'paypal' == $order-&gt;payment_method &amp;&amp; ! $sent_to_admin ) {
              echo 'my text:';
          } 
  }
  </code></pre>
  
  <p>I have tried with additional conditionals, like ! <code>$order-&gt;has_status( 'processing' )</code>, but nothing is working. Any help?</p>
