# Mobile app notification settings
## Accessing contact information & notification rules
This section walks you through managing your notification contacts (email, phone, push devices) and setting up notification rules in the ilert **mobile app**. If you’re looking specifically to configure **critical alert behavior** (e.g., bypassing Do Not Disturb), please see our [**Critical Alerts**](https://docs.ilert.com/mobile-app/mobile-app-notification-settings/critical-push-notifications-and-dnd-overrides) article.
1. Open the navigation by tapping on the menu icon on the top left.
2. Select the **Gear Icon** → **Contact information | Notification rules**
## **Contact information**
ilert enables you to add and verify multiple contacts, then activate channels to deliver alerts.
### Email addresses
* Tap **Add email** and enter your address.

## Notification rules
Define when and how you want to be notified for each event type.
### Rule types
| Rule Type | Description |
| -------------------------- | -------------------------------------------------------------------------------------------------------------------- |
| **High-priority alerts** | Notifies you when a high-priority alert is assigned (on creation or when added as a responder). |
| **Low-priority alerts** | Notifies you when a low-priority alert is assigned (on creation or when added as a responder). |
| **Alert status updates** | Notifies you when you’re already assigned to an alert and its status changes (e.g., another user accepts the alert). |
| **Incident notifications** | Notifies you when you’re added to an incident as a subscriber (on creation or when added manually). |
| **On-call notifications** | Notifies you at a specified time before your on-call shift begins (e.g., 15 min prior). |
### Creating a notification rule (Example: High-Priority Alerts)
Follow these steps to set up a rule that sends you an **email** **3 minutes** after a high-priority alert is created:
1. **Tap + Add notification rule**
2. **Configure the rule**
* **Contact & Channel:** Email
* **Timing:** Delay by 3 minutes
3. Save the Rule
Alert notifications in ilert are bi-directional; you can respond to a notification using the same channel on which you were notified (without logging into ilert), e.g., by replying to an SMS.
You have the following response options:
1. Acknowledge the alert
2. Mark the alert as resolved
3. Escalation to the next user in the alert's escalation policy
