Deprecated ---------- ### After release 1729 Field name Importance Data type Referential integrity Description **Preferences** Recommended String   This represents the subscription preferences of the customer. It uses the following convention: “DNE=Y&DNC=N&DNM=U”, all in one field. DNE, DNM, DNC and DNT have each been split into their separate columns (DoNotEmail, DoNotMail), with the same conventions for their respective values. This makes the merging of preferences across records much more granular and easier to manage for complex use cases. If you are already using this “Preferences” field, you can keep using it in your data feeds. You must not use both at the same time. Any information from the new columns (DoNotEmail) are overridden in the **Preferences** field.
