# Notification

> Contacts, contact groups, and email delivery on Datum Cloud — the notification.miloapis.com service.

Datum Cloud manages notification recipients and email delivery through the `notification.miloapis.com` API. You declare the people you contact, organize them into reusable groups, and send email — either one message or a broadcast to a group, optionally rendered from a shared template. Contacts, groups, memberships, and email resources are all created with `datumctl apply -f` and read with `datumctl get` and `datumctl describe`.

<Warning>
  The Notification API is **alpha** (`v1alpha1`). Fields and behavior may change in backward-incompatible ways between releases.
</Warning>
