Attach a ZIP archive to an email

This is a legacy StuffIt droplet utility from an era (late 1990s–early 2000s) when the StuffIt suite dominated Mac file compression. StuffIt itself has been abandoned for years — the company (Allume Systems) ceased development and there is no native Apple Silicon version. The bundle ID pattern (com.stuffit.droplet) indicates this is not a standalone application but a small helper component, and there is no evidence of modern maintenance or native builds. The app will continue to run under Rosetta 2 on current Intel Macs, but Apple is removing Rosetta from macOS 28 in September 2028, so this droplet will stop working on that release. For modern file compression, use the built-in Archive Utility (which compresses to ZIP by default and is included with macOS), the free open-source utility Keka, or the open-source command-line tool 7-Zip. If you need to attach compressed files to email, the Mail app's file attachment interface works seamlessly with these modern tools, or use a drag-and-drop workflow with Keka instead.
