Mbox Splitter Pro splits large MBOX archives into individual email files — drag-and-drop, batch processing, and full attachment preservation. Built natively for macOS.
Mbox Splitter Pro handles the heavy lifting — split massive MBOX exports from Gmail, Thunderbird, or Apple Mail into individual, searchable email files.
Just drag your MBOX file onto the app window. No command line, no configuration, no learning curve. It just works.
