What is removed from an email list when a list level unsubscribe occurs?

When a list level unsubscribe occurs, the email address is specifically removed from the associated list while still remaining in the overall subscriber database. This means that although the subscriber will no longer receive emails that are sent to that particular list, their data is retained within the system for other potential marketing engagements or for reporting purposes. Retaining the subscriber's information allows for better management of consent and preferences without losing any valuable historical data associated with that subscriber.

The other options present incorrect implications about data handling upon an unsubscribe action. For example, permanently deleting the email address outright would eliminate any possibility of future contacts, while simply retaining all subscriber data without any action taken contradicts the purpose of unsubscribing from that specific list. Flagging the email address for manual review suggests a level of ongoing oversight that does not occur in a standard unsubscribe scenario.
