List name.

Kind of identifier the list holds. Identifier lists: hem, email, uid2, eid, ip, maid. Record lists: contact, account, domain, zipcode, phone.

Deliberately not constrained to that list. The column is stored as given and the API does not enforce a set, so a list created by an integration carries whatever type that integration reported. Those eleven are what is in use today, not a guarantee. Match the ones you handle and pass the rest through rather than rejecting them.

Where the list came from. Supplied directly: upload, csv_upload, import, manual. Produced by an export run: export. CRM sync: salesforce, hubspot. DSP integration: delivrdsp, delivrdsp_events, delivrdsp_uid2.

Unconstrained for the same reason as type, and this is the column it has actually happened to: several of the values above reached production through an integration before any document named them. Treat an unrecognized value as data rather than as an error.
