選択肢
- It does not have a text field holding the full postal address, so the send cannot connect its rows to subscriber records.
- It is not stored inside a shared folder with a descriptive name, so the send cannot connect its rows to subscriber records.
- It is not marked as sendable with a field related to the subscriber key, so the send cannot connect its rows to subscriber records.
- It does not have a retention policy with a defined number of days, so the send cannot connect its rows to subscriber records.
