After a contact is added to the List, it will not be automatically removed as in a segment, but there is an exception, if you select "Remove from the list when they unsubscribe" when editing the list, the contact will be automatically removed from the list after the contact unsubscribes.
Why does uShopAid support this feature? uShopAid recommends that only consumers whose email subscription is subscribed be retained on the List. After consumers unsubscribed, it is recommended to remove them from the list immediately. If you manually remove these consumers who have unsubscribed, it is a very time-consuming thing, and it may cause some unpredictable consequences due to the untimely removal. Therefore, uShopAid provides this automatic removal function to help you solve this problem.
