- Unsubscribed covers the record across all Partitions.
- If you have a unique "brand unsub" then you need to ensure you have a Subscription Center. Be careful because the person may think they will never hear from you again, when it is just for one brand.
So if the "unsubscribed" isn't checked that means they can still be subscribed to our other brands, correct? That is what we would want.
I need to dig further and check about a subscription center.
