In their own words
InboxSweeper
InboxSweeper is a free, open-source tool for clearing old promotional mail and newsletters and unsubscribing from mailing lists. It supports Gmail fully; Yahoo and other IMAP inboxes are experimental. Choose among three sweep modes: Sloth targets mail older than two years, Normal mail older than one year, and MadMax includes recent promotional mail. Their respective run caps are 25, 50, and 100 senders. Before moving messages, sweeps show counts; financial, security, payment, receipt, and government mail is protected. You can unsubscribe, move selected messages to Trash, or report senders as spam. Trash messages are described as recoverable for about 30 days. One-click and mailto unsubscribe options are supported; web-link-only options are flagged for manual handling. The tool runs on your computer and says it does not upload mail, credentials, or tokens. It offers a local browser interface, Windows executable, terminal CLI, and AI-agent instructions. It uses a scoped app password rather than Google OAuth, with credentials stored in macOS Keychain or a locked file.
