Customize the email address(es) that you would like to receive notification when a registration/application has been submitted. Standard, Pro and Enterprise customers can customize the email address to which notifications are sent whenever a new registration form is submitted. This setting is made via the System Setup Wizard (step 3a - https://www.volunteermatters.net/vm/wizards/SystemSetup/SelfRegSettingsEdit.do) in the "Email Notifications" field.
It is not required to send email notifications. If configured properly you could simply log into the system periodically to retrieve a list of contacts with the 'N - New' status.
