From My preferences you can view all active alerts, edit them, or delete the ones you no longer need.
How to access your alerts
Click My preferences, at the bottom of the sidebar.
Go to the Notifications tab.
Find the Alerts section.
Edit an alert
Click the pencil icon (✏️) next to the alert you want to modify.
The full wizard opens again (What / How / When / Name), where you can change whatever you need.
To turn Slack or email notifications on or off, you don't need to edit the alert: do it directly on its card.
Delete an alert
Click the trash icon (🗑) next to the alert.
Confirm the deletion.
Note: alerts are not tied to saved views; deleting an alert does not affect your views.
