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.
MailMop
MailMop is a Gmail inbox-cleaning tool for identifying clutter and managing messages in bulk. It groups clutter by sender and shows message counts, then provides actions such as deleting, blocking senders, unsubscribing, marking messages read, applying labels, and creating filters. Gmail headers are analyzed through the Gmail API; when message content is needed to locate unsubscribe links, processing occurs in the browser rather than on MailMop servers. The service says it handles inboxes up to 500,000 emails, while its FAQ states there is no processing limit. MailMop works with one inbox at a time, but one Pro subscription covers all of a user’s inboxes. Basic is free and includes unlimited analysis, sender statistics, unsubscribe, export, and Gmail links. Pro costs $1.89 a year, billed annually at $22.68/year, adding one-click bulk actions, bulk delete, advanced filtering and labels, and sender blocking. It is available on the web or can be self-hosted for free.
