You can unsubscribe from receiving Program Listing or Discover RPL emails or update your selection preferences using the links in the footer of the email. You won't be able to manage your email subscriptions preferences from your library account - this is a separate service.
Program listings will be delivered to your inbox every month from the date you signed up. For example, if you signed up on May 4, your program listings will be sent to your on the 4th of the next month.
