# Notifications

> Send a notification from an automation, and who receives it.

You can send a notification from any automation. It appears in the **notification dialog** you open from the navigation bar, and in the **notifications tab** inside your project.

Automations create them with the [`post_notification`](/apps/colossal-app/actions#notification) action.

## Who receives it

You cannot choose. A notification from an automation reaches whoever that automation belongs to: the person who created it, whoever set that run going, plus anyone added to an agent that uses it. A builder who has never touched the automation is not notified.

So "notify me" on an automation you built reaches you. On an automation inside a shared agent, it also reaches that agent's people. There is no recipient setting, and no way to send to a named person or an outside address from this action - use the email, Slack or Telegram actions for that.

## Severity

Severity sets how a notification reads, not who gets it or what it can do:

* **info**
* **suggestion**
* **warning**
* **action\_required**
* **celebration**

Choose it honestly. Marking something **action\_required** does not change who is notified, does not add buttons, and does not create an approval. Approvals are a separate [step type](/automations/step-types#ask-a-person-to-approve).
