You will see the automated email templates and be able to modify them. By default, the language selected in Site Settings → More → Website language is used in the emails. If the language is not yet specified, you will first need to select it.
You can change the email subject and body text by using the variables displayed in the tip for each email type. They should be added without modifications, exactly as they appear in the template. For instance, if you paste the {{login}} variable, the Members Area login (user's email) will be automatically inserted in the email.
The variables allow you to automatically personalize emails for each user by adding their login and password. You can also insert a personal login page URL and the domain of the Members Area website in the email.
