N8N can be used for more advanced conditional notification use cases. For example, you want only to get notified if two out of a specified list of devices is down. Or you can use other plugins to process the notifiations further. The below is a simple example of sending an email on a webhook.
See sample JSON if you want to see the JSON paths used in the email template below
Events count: {{ $json["body"]["attachments"][0]["text"]["events"].length }}
New devices count: {{ $json["body"]["attachments"][0]["text"]["new_devices"].length }}
