Deprecated: field set columns
get_pack_details: deprecated; use list_field_sets instead.
Deprecated: lists the columns of one field bundle. Use list_field_sets instead. list_field_sets returns every field set with its exact columns and credits per record. It stops working 12 months after the new tools launch, after three emailed notices; https://emailmovers.com/mydatahub/docs/migrate maps every call. Lawful basis is UK GDPR Article 6(1)(f) legitimate interests; email audiences include corporate subscribers only by default (PECR), so sole traders and ordinary partnerships are left out unless the toggle is changed.
