Hello @BobbyJ8. You certainly can merge contact lists together! After going into your Contacts and clicking on View All Lists, you can select which lists you would like to merge and then click the Merge button. You will then be prompted to create a new list name. When you merge or copy contacts into other lists, the original lists won't be deleted and duplicate contacts are automatically removed. Also, if you have more than 10,000 contacts on a single list, the ability to merge your lists this way may not be available.
