 Next, in your mailer you'll need to call `view_mail` with the first parameter being the ID of the notify template, followed by a hash of email headers e.g:
 
 ```ruby
 class MyMailer < Mail::Notify::Mailer
     def send_email
-        notify_mail('YOUR_TEMPLATE_ID_GOES_HERE',

+#### With optional Notify arguments
+
+It's possible to pass two optional arguments to Notify:
+
+- `reply_to_id`: This is an email reply-to address specified by you to receive replies from your users
+- `reference`: A unique identifier you can create if necessary. This reference identifies a single unique notification or a batch of notifications
