Email notifications are used in Incentive to send out information to users, for example when a user is mentioned or when some likes or comments on something a user posted.
To enable email notifications you must first configure the installation's Smtp settings. You should then go to Manage, Daemons, Send notifications to select the email notifications you want to activate:
- Email notifications, sends an mail every time a user gets a notification
- Daily digest, send a collection of everything that's happened during the day
Please note that a user can still disable email notifications for their user account by going to notification settings on their profile page.
