Identified - Due to a security concern, we have temporarily deactivated the Alerts API SMTP (email) delivery option that is available for testing and evaluation purposes only. To continue testing the Alerts API on either the Flightstats or Sky platforms, please configure delivery to an HTTPS endpoint that accepts POST requests, as per https://developer.cirium.com/apis/cirium-sky-api/flight-alerts. We apologise for any inconvenience and will provide an update as soon as there is progress to report.
