Mail Incinerator is a macOS utility designed to remove locally stored Apple Mail cache data that can occupy significant disk space over time.
Apple Mail downloads and stores message data locally, including attachments and cached content. Mail Incinerator scans these locations, shows what will be removed, and permanently deletes selected cache files.
The app operates only on local data stored on your Mac. It does not modify mail accounts, server-side messages, or Mail settings.
