# AWS managed notifications in AWS User Notifications
AWS managed notifications

 AWS managed notifications are notifications generated by default. Currently, only AWS managed notifications from AWS Health are supported in User Notifications. You can view and manage AWS managed notifications across services and Regions in the Console Notifications Center. 

AWS managed notifications are automatically available in the Console Notification Center and sent to account contacts ([primary contact email](https://docs.aws.amazon.com/accounts/latest/reference/manage-acct-update-root-user.html) and [alternate contact emails](https://docs.aws.amazon.com/accounts/latest/reference/manage-acct-update-contact-alternate.html)). You can manage the account contacts subscriptions of AWS managed notifications and set up additional delivery channels, including [notification-contacts](https://docs.aws.amazon.com/notificationscontacts/latest/APIReference/Welcome.html), [Amazon Q Developer chat notifications](https://docs.aws.amazon.com/chatbot/latest/adminguide/what-is.html), [AWS Console Mobile App](https://docs.aws.amazon.com/consolemobileapp/latest/userguide/what-is-consolemobileapp.html) push notifications, and the [User Notifications API](https://docs.aws.amazon.com/notificationscontacts/latest/APIReference/Welcome.html).

You can aggregate AWS managed notifications across accounts within the same organization to reduce the total number of notifications you receive. For more information, see [Aggregating and deduplicating AWS managed notifications in AWS User Notifications](managed-notification-aggregation.md). 

**Note**  
 Viewing and modifying AWS managed notifications requires specific [read and read-write permissions](resource-level-permissions.md#rlp-table). 

For help with AWS Health managed notifications, see [Manage notifications in AWS User Notifications](https://docs.aws.amazon.com/health/latest/ug/manage-user-notifications.html) in the *AWS Health User Guide*.

## Adding delivery channels for AWS managed notifications in AWS User Notifications
Adding delivery channels for AWS managed notifications

You can add delivery channels from the console to have your AWS managed notifications sent to other locations. Available delivery channels include, email addresses, and chat channels

**Note**  
Emails you receive from User Notifications are sent from the domain `@aws.com`. The prefix of the emails you receive reflect the AWS service sending the communication. For example, notifications from AWS Health are sent from the email `health@aws.com`.  
Aggregated notifications are sent from `notifications@aws.com`. If your organization uses an email allow list, add the `@aws.com` domain to ensure you receive all User Notifications emails.

**To add delivery channels**

1. Open User Notifications in the [AWS Management Console](https://console.aws.amazon.com/).

1. In the navigation pane, choose **AWS managed notifications subscriptions**.

1. In **Delivery channels**, choose **Add delivery channels**.

1. In **Emails**, choose or enter the recipient's email address.
**Note**  
A verification email is sent to newly added email addresses. You can generate another verification email for pending addresses by choosing **Reverify**. Verified emails have a green checkmark next to the email address when added as a **Recipient**.  
The recipient must be signed in to the AWS account that added the email address to complete the verification process. The verification link directs to the AWS Management Console.
**Tip**  
You can use your email distribution lists as an email delivery channel to easily subscribe multiple email addresses to User Notifications with a single verification flow. You can separately add and remove emails to the distribution list without requiring further verification with User Notifications. 

1. For **Name**, enter the recipient's name.

1. (Optional) Choose **Add another recipient** to add more recipients.

1. (Optional) Add mobile devices:

   1. In **AWS Console Mobile Application** select mobile devices to add.

# Aggregating and deduplicating AWS managed notifications in AWS User Notifications
Aggregating and deduplicating AWS managed notifications

AWS managed notification aggregation is a standard feature available to all management accounts and delegated administrators that have [enabled trusted access](uno-orgs.md) with AWS Organizations. Managed notification aggregation organizes and streamlines your view of events that impact multiple accounts within an organization. User Notifications uses information from AWS Organizations to aggregate events across accounts within an organization and provides an organized view of events affecting multiple accounts.

 In addition, User Notifications deduplicates emails when an account contact is shared between the management account (or delegated administrator) and the member account. This reduces the total number of individual notifications you receive. 

## Event aggregation process


 AWS managed notifications use an event aggregation logic that combines related events to reduce notification volume while maintaining timely delivery of critical information. Events are aggregated based on two key factors: 

**Topics**
+  Communication ID - Events sharing the same `communicationId` are considered related 
**Note**  
Events are sent to User Notifications via an API integration that uses the same format as Amazon EventBridge. For more information, see [Reference: AWS Health events Amazon EventBridge schema](https://docs.aws.amazon.com/health/latest/ug//aws-health-events-eventbridge-schema) in the *AWS Health User Guide*.
+  Time window - Events with the same `communicationId` are aggregated within specific time periods based on managed notification sub-category:     
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/notifications/latest/userguide/managed-notification-aggregation.html)

## Aggregating AWS managed notifications


User Notifications aggregates event information across accounts as follows:
+ **The same event occurs across multiple accounts within the same organization** – The management account and delegated administrators receive a single aggregate notification containing information about all affected accounts. Each impacted member account receives an individual notification specific to their account.

**Note**  
Aggregation behavior is identical for both the management account and delegated administrator account.

## Deduplicating AWS managed notifications


User Notifications deduplicates event information across account contacts as follows:
+ **An account contact (root user email or alternate contact email) is shared between the management account or delegated administrator and a member account** – User Notifications sends the aggregate notification about all accounts to the management account or delegated administrator. Individual email notifications to the shared email addresses in member accounts are suppressed.
+ **An account contact (root user email or alternate contact email) is shared between member accounts, but not the management account or the delegated administrator** – Individual notifications are sent per account for each account contact as default notifications. 
+ **Plus address handling** – Plus addressing is a method used to create unique, receive-only email addresses based on an existing email address. You can use plus addressing by adding a plus sign (\$1) and any word at the end of your email address. For example, email@example.com and email\$1devops@example.com. User Notifications treats email addresses with plus addressing as the same email address. This prevents the same email from being sent to the same inbox multiple times.

Deduplication only applies to account contact emails. AWS managed notifications sent to other member account delivery channels (for example, the Notification Center) are always sent.

**Note**  
User Notifications won't deduplicate events across shared account contacts within the same account. For example, email@example.com and email\$1devops@example.com. We recommend you unsubscribe identical account contacts. For more information, see [Adding and removing account contacts for AWS managed notifications in AWS User Notifications](Add-remove-account-contacts.md).
