When IT departments migrate enterprise systems, merge corporate databases, or clean legacy communication infrastructure, they segment user records by domain. Grouping @orange.fr , @wanadoo.fr , and @sfr.fr addresses into a single text file allows system administrators to process French consumer accounts efficiently without affecting international domains like Gmail or Outlook.
