+The specified `email` or `subscription_id` will be matched against your existing subscribers.
+If an existing subscriber is found, they will be enrolled immediately.
+
+Looking to enroll new subscribers? Use the **[Subscriptions Create](https://beehiiv.stoplight.io/docs/v2/1a77a563675ee-create)** endpoint instead and specify the `automation_ids` param.
