# GitLab Notification Emails

GitLab has a notification system in place to notify a user of events that are important for the workflow.

## Notification settings

You can find notification settings under the user profile.

![notification settings](img/notification_global_settings.png)

Notification settings are divided into three groups:

* Global Settings
* Group Settings
* Project Settings

Each of these settings have levels of notification:

* Disabled - turns off notifications
* Participating - receive notifications from related resources
* Watch - receive notifications from projects or groups user is a member of
* Global - notifications as set at the global settings
* Custom - user will receive notifications when mentioned, is participant and custom selected events.

#### Global Settings

Global Settings are at the bottom of the hierarchy.
Any setting set here will be overridden by a setting at the group or a project level.

Group or Project settings can use `global` notification setting which will then use
anything that is set at Global Settings.

#### Group Settings

![notification settings](img/notification_group_settings.png)

Group Settings are taking precedence over Global Settings but are on a level below Project Settings.
This means that you can set a different level of notifications per group while still being able
to have a finer level setting per project.
Organization like this is suitable for users that belong to different groups but don't have the
same need for being notified for every group they are member of.
These settings can be configured on group page under the name of the group. It will be the dropdown with the bell icon. They can also be configured on the user profile notifications dropdown.

#### Project Settings

Project Settings are at the top level and any setting placed at this level will take precedence of any
other setting.
This is suitable for users that have different needs for notifications per project basis.
These settings can be configured on project page under the name of the project. It will be the dropdown with the bell icon. They can also be configured on the user profile notifications dropdown.

### Issue / Merge Request events

In all of the below cases, the notification will be sent to:
- Participants:
  - the author and assignee of the issue/merge request
  - authors of comments on the issue/merge request
  - anyone mentioned by `@username` in the issue/merge request title or description
  - anyone mentioned by `@username` in any of the comments on the issue/merge request

    ...with notification level "Participating" or higher

- Watchers: users with notification level "Watch"
- Subscribers: anyone who manually subscribed to the issue/merge request
- Custom: Users with notification level "custom" who turned on notifications for any of the events present in the table below

| Event                  | Sent to |
|------------------------|---------|
| New issue              | |
| Close issue            | |
| Reassign issue         | The above, plus the old assignee |
| Reopen issue           | |

In addition, if the title or description of an Issue or Merge Request is
changed, notifications will be sent to any **new** mentions by `@username` as
if they had been mentioned in the original text.

You won't receive notifications for Issues, Merge Requests or Milestones
created by yourself. You will only receive automatic notifications when
somebody else comments or adds changes to the ones that you've created or
mentions you.
