# Delivery channels
<a name="notification-center-channels"></a>


| Channel | Type | Description | 
| --- | --- | --- | 
| In-app |  `inApp`  | Writes a notification item to each recipient’s inbox in the Spatial Data Portal. Notifications appear in the bell icon in the portal navigation. Items expire after 90 days. | 
| Slack |  `slack`  | Posts a formatted message to a Slack webhook URL stored in AWS Secrets Manager. The webhook is the destination — recipients are not used for routing. | 
| Email |  `email`  | Sends an email via Amazon SES to each recipient’s address resolved from their Cognito user profile. | 

Each notification rule targets exactly one channel. To deliver to multiple channels, associate multiple rules — one per channel — to the same template. Each rule retries independently.
