List membership Filters Not Working As Expected

I’ve created a few base lists that include all of our customers and prospects (two separate lists). I have then created separate lists to use as filters that contain our more complex logic that define our segments -- like business size (SMB, Mid Market and Enterprise). But when I go to build a new list using the logic:

List membership
is member of MTKG - BASE LIST - Prospects
is member of MKTG - FILTER - Segment - Business
is member of MKTG - FILTER - Company Size - Mid Market

It doesn’t give me the output I am expecting. Any ideas?

Hi @HayleyHolli,

Can you share a bit more context? In your final list, do you want only contacts who are in all three lists? If that’s what you’re expecting, what is happening instead? Can you please share a screenshot of the filters of the final list?

Just to confirm, if you want only contacts who are members in all three lists, have you used the AND operator? (is member of MTKG - BASE LIST - Prospects AND is member of…)

Best regards

I figured it out. :sweat_smile: I changed my list name and was using the wrong one. I appreciate you taking the time to reply. :slightly_smiling_face:
