# Notification groups
Notification groups are used throughout Brigge, wherever you configure email message recipients - for example, in *Pipeline settings* for [run failure notifications](/documentation/brigge-for-transformers/pipelines/pipeline-settings.md#failure-notifications), or in [*Notification* nodes](/documentation/brigge-for-transformers/pipelines/pipeline-nodes/notification-node.md).
When [creating notification groups](#creating-a-notification-group), you add recipients - these can be external contacts (added via their email address) or other platform users associated with your organisation. As soon as you add a recipient, an opt-in email is sent to the associated email address.
{% hint style="warning" %}
Recipients will not receive notification emails until they activate the 'opt-in' link in the message they receive. If a user advises that they are not receiving notifications, the most likely reason is that they did not opt in. You can [resend an opt-in email](#resending-a-notification-opt-in-email) at any time.
{% endhint %}
## Working with notification groups
Viewing existing notification groups
To view existing notification groups for your organisation, select *Settings* from the navigation menu, then select *Notification groups* from the *Company management* section. All existing notification groups are shown. For example:
From here, click any group to view or [update the content](#viewing-and-updating-notification-group-recipients). For example:
Creating a notification group
{% stepper %}
{% step %}
**Launch the create notification group wizard**
Access existing *Notification groups*, then click the `create notification group` button. For example:
{% endstep %}
{% step %}
**Provide a name for the notification group**
Enter a `name` for this group, then click the `save` button. For example:
{% endstep %}
{% step %}
**Add recipients**
Click the `add recipients` button:
Now you can choose to add recipients by their email address (typically used for external users) - for example:
Or, set the `recipient type` to `platform user` and select other platform users within your organisation (notification emails are sent to their [Brigge account email address](/documentation/users.md#viewing-and-updating-user-details)):
As soon as you add a recipient, an opt-in email is sent to the associated email address.
{% hint style="warning" %}
Recipients will not receive notification emails until they activate the 'opt-in' link in the message they receive. If a user advises that they are not receiving notifications, the most likely reason is that they did not opt in. You can [resend an opt-in email](#resending-a-notification-opt-in-email) at any time.
{% endhint %}
{% hint style="info" %}
When adding platform users, you can select from any users within your organisation.
{% endhint %}
{% hint style="info" %}
Having added a recipient's email address, you can't change it subsequently. If you find that an email address is incorrect, [delete it](#deleting-notification-group-recipients) and add the recipient again.
{% endhint %}
{% endstep %}
{% endstepper %}
Resending a notification opt-in email
As soon as you add a recipient to a notification group, an opt-in email is sent to the associated email address. Recipients will not receive notification emails until they activate the 'opt-in' link in the message they receive. If a user advises that they are not receiving notifications, the most likely reason is that they did not opt in.
You can resend an opt-in email at any time. To do this, [access the relevant notification group](#viewing-existing-notification-groups) and click the `resend opt-in` button for the user. For example:
Deleting notification group recipients
To delete existing recipients from a notification group, [access the relevant notification group](#viewing-existing-notification-groups) and click the `delete` (trash) icon for the user. For example:
