If you are an admin of the system and your user profile will be moved to the Leavers list and not deleted, your Plugin Schedules will continue to run for your leaver account, and the emails will be redirected to the notification admin of the system.
However, the notification admin will not have access to these schedules, as Plugins are user specific, so you would still be the only person that could cancel or amend these schedules in the future.
We recommend setting up the schedules again from another's admin account.
