Mail Notification Settings

By default, most of the sample pages are configured to send an email upon completion of the task demonstrated on the page. If you want to turn notification off, then edit the notification section of the SPEUserPages configuration object. The configuration allows to enable/disable email notification for every page individually. See Configuring the Filter for more details.

Make sure that you configure the SMTP server. To do this, click Configure, then Servers and navigate to the Email Template tab for the SMTP server.
