The third roll-up status you have is the A.I. Tags Marketing Subscribed value. This is driven by a basic ruleset and can be a useful, less pessimistic, method of creating your GDPR list.
This will add one of the following values to each Customer:
- Unsubscribed: The Customer has to have been found to have at least one Unsubscribe and no Subscribes.
- Partial: The Customer has been found to have a mix of Subscribe and Unsubscibes across your datasets.
- Subscribed: The Customer has been found to have only Subscribes across your datasets. No unsubscribes.
- Unknown: The Customer has been found to have no Subscribe or Unsubscribe information across your datasets.

You can of course mix these attributes with the raw TRUE/FALSE subscribe information in each dataset to create the perfect mix.
