+
+The first-time usage notifications feature sends email notifications when there is first-time billable usage for a new product not included in your current contract. Emails are sent approximately 48 hours after the usage first occurs during a given month.
+
+After enabling the feature, a new **Usage Notifications** tab is added to the parent organization's **Plan and Usage** page. On this tab, there is a list of all products covered by the functionality. Unchecking a box stops notifications for that product for all users within the account. If any first-time usage outside of your most recent active contract is detected, users do not receive a notification for any unchecked products.

+
+Any user with _Usage Notifications Read_ or _Write_ permissions receives emails. For most organizations, this means any admins.
+
+If your Datadog account is a multi-organization, parent organization users with permissions receive email notifications of usage in child organizations. These emails indicate which child organization generated the usage, and the product which usage was generated for. Child organization users with this permission receive emails for their organization only.
