What's the difference between send table data (export), send table data (enrichment), and Write to other table?

Write to Other Table is the deprecated legacy method for transferring data between tables. Send table data is the modern replacement with two methods: Send row (export) transfers each complete row as-is to another table for moving/exporting data, while Send row for each item in a list (enrichment) breaks down lists within cells and creates separate rows for each item in the destination table. The key difference is export moves complete rows while enrichment expands lists into individual rows for further processing. Reference: clay.com
