My understanding is that if you build a segment with the device co-op as the profile merge rule, you can ONLY reach people who are in the device co-op. This would severely limit the segment size and exclude those who qualify for the segment based on the traits but are not part of the device co-op.
How have others implemented segments using the co-op? For something simple like a suppression use case does it make sense to create two segments – one with a merge rule of “No Authenticated” to maximize the scale of the segment and another with the “Co-op” merge rule to make sure you’re finding your audience across multiple devices?
Can someone confirm if my initial understanding is correct and the best way to use the co-op? I want to maximize the size of my segments but also benefit from finding users across multiple devices.
After speaking with someone at Summit, I was assured the Co-op is large enough there are very few people that would be missed by only using this profile merge rule, so I have been using this exclusively with positive results thus far.
