To edit the default Email & SMS settings, go to Settings > Email & SMS.

Here, each of the types of emails are split up by tabs of who is receiving them at the top of the page. To ensure the organisation name and reply email address are correct, go to the General tab and click on General.

To make changes to any of the notifications you are sending out, just click the yellow pencil button to edit the content and you can change subject lines, text of the email and any other options relevant to that notification.

Once you are happy with any changes, click save.
