Notification center View and manage all your Ravenna notifications in one place. Approvals, assignments, comments, and team activity surface in a single view, helping you stay focused without jumping between channels and individual tickets. ![Notification center](https://d1kzozfjh72w00.cloudfront.net/documentation/screenshots/platform/notifications/centre.png) *** Notification events Control which types of updates generate notifications. Each event type can be enabled or disabled for Slack and email delivery independently. Notifications when tickets are assigned or unassigned to users. * New ticket assignments * Ticket reassignments between users * Removal from ticket assignments Enabled by default for both Slack and email notifications. Approval-related notifications for sign-off workflows. * Approval requests for tickets requiring sign-off * Approval decisions (approved/declined) * Changes to approval requirements **Slack**: Approval notifications are always delivered and cannot be toggled off by users or organization admins. This ensures approvers never miss time-sensitive requests. **Email**: Approval notifications are configurable and enabled by default. Communication and collaboration updates. * New messages on tickets you’re following * Follower additions and removals * @ mentions in ticket conversations * File attachments and updates Enabled by default for both Slack and email notifications. Ticket lifecycle notifications. * Status changes (open, in progress, resolved, closed) * Ticket resolutions and closures * Reopened tickets * Archive and unarchive actions Enabled by default for both Slack and email notifications. Service level agreement notifications. * SLA breach warnings * SLA violation alerts * Time-based escalations Enabled by default for both Slack and email notifications. Learn more about [configuring SLAs](/documentation/automate/slas) Granular property change notifications. * Priority changes * Tag additions and removals * Channel transfers * Custom field updates * Due date changes Disabled by default to reduce notification volume. Enable only for users who need detailed property change tracking. *** Delivery channels Notifications deliver through Slack and email. Configure delivery preferences for each notification event type independently. Direct messages provide private, focused notifications for individual users. Configure when Ravenna sends DMs: * **For Slack-originated tickets**: Choose between thread notifications, DM notifications, or both * **For web and email tickets**: Enable DM notifications for non-Slack originated tickets * **Approval workflows**: Approval requests always generate Slack notifications regardless of user preferences or origin. This cannot be disabled Learn more about [Slack integration](/integrations/slack/overview) Public channel notifications are controlled by channel settings: * **Request channels**: Controlled by Silent Mode and Granular Updates settings * **Triage channels**: Team notifications for ticket management * **Ephemeral messages**: Contextual notifications visible only to specific users **Silent Mode**: When enabled in channel settings, silent mode prevents ticket mirrors from appearing in request channels and automatically excludes requesters from email notifications. This reduces notification noise while keeping followers, assignees, and other stakeholders informed. Learn more about [Slack channels](/integrations/slack/overview) and [triage channels](/integrations/slack/triage-channel) Email notifications provide backup delivery and offline access: * Digest emails for daily and weekly summaries * Critical alert emails for high-priority issues * Backup delivery when Slack is unavailable **Requester exclusion**: When silent mode is enabled in channel settings, requesters are automatically excluded from email notifications. This prevents users from receiving email updates about tickets they created, reducing notification volume while keeping other participants informed. Learn more about [email integration](/integrations/email/overview) *** Configuring notifications Configure notification preferences at the organization level to set defaults for all users, or at the individual user level to customize personal notification settings. Organization admin configuration Organization admins set default notification preferences for all members. These defaults provide a baseline experience while allowing individual users to customize their own settings. Go to **Settings → Organization → Notification Policies**. Set organization-wide defaults for Slack and email notifications for each event type. Changes apply immediately to users who haven’t customized those specific settings. **Understanding organization defaults** When managing organization notification policies, keep these behaviors in mind: * **User customizations persist**: If a user has customized a specific setting, changing the organization default won’t affect them * **Per-setting granularity**: Customization is tracked individually for each notification type (for example, “Assignments” for Slack) * **No bulk reset**: You cannot force all users back to organization defaults. Users must individually reset their customized settings User configuration Individual users customize notification preferences to control when and how they receive updates. Go to **Settings → Notifications** in your user profile. Settings marked with “Using default” follow your organization’s policies. Toggle any setting to customize it. Your preference persists even if organization defaults change. Click the reset icon next to any customized setting to revert to your organization’s default. Once you customize a notification setting, your preference takes precedence over organization defaults until you manually reset it. *** Troubleshooting If you’re not receiving expected notifications: Verify your individual notification settings in **Settings → Notifications**. Check that you are properly assigned or following relevant tickets. Ensure the specific notification type is enabled for your preferred delivery channel (Slack or email). Check with your admin if organization-level defaults have changed recently. If you’re receiving too many notifications: Turn off “Ticket properties” notifications to reduce volume significantly. Disable notification types that aren’t relevant to your role or responsibilities. Consider using email digest notifications instead of real-time Slack notifications for less urgent updates. Unfollow tickets that no longer require your attention. Slack approval notifications have special handling that differs from other notification types: * Always delivered via Slack regardless of user or organization preferences * Cannot be toggled off in Slack notification settings (not shown as a configurable option) * Include action buttons for quick responses * Update automatically when decisions are made Email approval notifications remain configurable and can be enabled or disabled like other notification types. Slack approval notifications always deliver because they require timely action. If you’re receiving approval notifications inappropriately, review your role assignments and approval workflows.
