The common notification rule is a global email notification rule which you can create and choose to serve as a default one for all newly created projects.

The common notification rule is overridden by project-level notifications rules. See Project email notifications for details.

Enabling/Disabling Common Notification Rule

To edit/disable a default notification rule (enabled by default):

1. Log in as Administrator (or a user who has the ‘Manage System Settings’ permission). If you are already logged in, skip this step.
2. Click through User menu | Settings | Notifications on the header menu.
3. Select the Common notification rule tab.
4. To disable: Clear the 'Make Common Notification Rule available in all projects' checkbox, or
5. To edit: Make changes as required. On the Notify creator option, see below.
6. You can select one of the 3 preset event selections: Key events, Nothing, or All(default).
7. Click 'Apply'.

Use the same process to enable the default notification rule.

The Always Notify Object Creator option

Messages and attachments added (created) by a user are not covered by this option. In other words, if you are the creator of a message or attachment, and this option is enabled, you will not be notified of the event of creating those.
