At this time there is not a way to archive your lists. As an alternative you can either 'favorite' the lists you do use so they appear on the top (https://knowledgebase.constantcontact.com/articles/KnowledgeBase/5479-favorite-a-list), or rename the other lists to include a description in the name saying it's archived (ex. "(Archived) General Interest").
Were you hoping for something that archives/displays it separately outside of the Contacts page?
Hi - is this something that has been added in as a functionality? I don't want to delete these lists, but I do want to "hide" them from my everyday lists. Thanks.
