  title: Set up alerts for failed workflow executions using Gmail
  description: >
    This system flow will help you set up alerts for failed workflow executions.
    Using this pattern, you can manage alerts on failure in one place.

    This flow sends an email alert with Gmail whenever a flow execution fails.

    If you have 2FA setup on your Google account, you'll need to set up an [App
    password](https://myaccount.google.com/apppasswords). Once you've generated
    an App password, save it as a secret which you can reference in the
    `password` property.

    For more information on creating App passwords, check out the guide
    [here](https://knowledge.workspace.google.com/kb/how-to-create-app-passwords-000009237).

    ## Restricting alerts using conditions

    You can restrict the flow to only send alerts for specific namespaces by
    adding an `ExecutionNamespaceCondition` to the trigger. You can read more
    about that in the [Administrator
    Guide](https://kestra.io/docs/administrator-guide/monitoring).
