Trying to create an un engaged segment for a sunset flow - Need clarification please

Hello @Louise1,

Thanks for sharing your question with the Klaviyo Community!

You can create a master list by either manually exporting all of your lists and importing them into a singular list or through segmentation and then converting the segment into a static list. Both of these options are detailed in the How to Combine Two or More Lists in Klaviyo Hep Center Article Klaviyo offers. Both strategies would work and would simply depend on your preference of which one you wanted to use.

Similar to what was detailed in the How to Combine Two or More Lists in Klaviyo article, you certainly can create a segment from multiple lists. When doing so, keep in mind you’ll want to use the OR rule as opposed to an AND rule when including multiple lists. This is because using the AND rule is exclusive while the OR rule is inclusive as detailed in the AND vs. OR Guide article. 

For example, if you wanted to use segmentation to evaluate subscribers in List A and List B, if you were using an AND rule, this would cross-reference the two lists and return a segment of customers who are subscribed to both List A and B. Meaning a contact must be a subscriber of both lists to be captured by the segment. On the other hand, using the OR rule for the same segmentation rule would return all customers present in List A or List B. Customers can be subscribers to either one of these lists and still be captured in the segment. 

Other resources I would suggest taking a look at are the How to Create an Unengaged Segment and Guide to List Cleaning articles to learn more about creating unengaged segments as well as some other Community posts that touch upon the same subject which i’ve included below:
