You can segment a subscriber list or data extension using data filters and use the segments during an automation.

Every subscriber in your account appears in the All Subscribers list. Subscribers added to a subscriber list join the All Subscribers list at the same time. Subscribers stored on data extensions join the All Subscribers list when you send your first message to that subscriber. If a subscriber is unsubscribed in the All Subscribers list, the subscriber is unsubscribed from all lists and groups. When a subscriber is set back to active on the All Subscribers list, the subscriber must also opt in for any other list and group separately. A subscriber can be unsubscribed on lists and groups and be active on the All Subscribers lists. 6. **[Exclusion Lists in Marketing Cloud Engagement](https://help.salesforce.com/s/articleView?id=mktg.mc_es_exclusion_list.htm&release=264.0.0&type=5)** An exclusion list is any list, group, or data extension you create in the application that at the time of send you select to exclude from the send. If your Email Studio account has subscriber key enabled, the system excludes using the subscriber key value.
