Main toolbar > Render Scene button > Render Scene dialog > Common panel > Email Notifications rollout
This rollout lets a rendering job send email notifications, as network rendering does. Such notifications can be useful when you launch a lengthy render, such as an animation, and don't care to spend all your time near the system doing the rendering.

Enable Notifications—When on, the renderer sends an email notification when certain events happen. Default=off.
Notify Progress—Sends emails to indicate rendering progress. An email is sent every time the number of frames specified in Every Nth Frame has completed rendering. Default=off.
Notify Failures—Sends an email notification only if something occurs to prevent the completion of a rendering. Default=on.
Notify Completion—Sends an email notification when a rendering job is complete. Default=off.
