By default when new users registered email features and some other features were set to on. I've changed the registration so that all new registrants have these features set to off. To make sure no one is getting unwanted email I've reset the following preferences for every member to off. These can be found on the under the preferences tab of the user control if you wish to enable them them.
Under the main preferences tab:
