Hi @Fly4Food,

Thanks for sharing your question with the Community.

You will need to add “AND” separators to your definition, using is not in list for lists 1-5. The segment would be defined as: is not in list 1 AND is not in list 2 AND is not in list 3 AND is not in list 4 AND is not in list 5. Since “AND” is exclusive (the user must meet all criteria separated by “AND” in order to qualify for the segment) that means this segment will give you everyone who is not a member of these lists. In other words, if they are a member of any of these lists, they will be excluded from the segment thus giving you your segment of people not in a list.

Thanks and have a wonderful rest of your week.

Thank you, I had used OR and ended up with everyone!
