"Subscription expiration" notification/event is configured in Tools & Settings > Notifications
These emails are generated during the Plesk daily task (/etc/cron.daily/50plesk-daily), which is running every night by default
Notifications are being sent separately related to each subscription.
It is not very convenient to receive such kind of notifications separately.
