GoodByEmail vs Trimbox

GoodByEmail analyzes an exported inbox to show which senders use storage and help users decide what to clean up. Users import an MBOX or Outlook PST file, then filter or sort senders by storage, email count or last received date. The app can identify mailing-list senders and supports one-click unsubscribing. It does not scan or delete messages automatically: users export their inbox and remove selected emails in their email client. The maker says mailbox processing happens locally, without uploading or storing email content, metadata or mailbox statistics on its servers. Scanning can work offline after an online login unlocks the app. The free version shows unordered results for everyone who has emailed the user; actionable cleanup insights require a license. Paid options include Lite at $9.99 a month, Plus at $14.99 a month and Pro at $19.99 a month. A Perpetual license costs $199 as a one-time purchase. The platform list includes macOS, Windows and self-hosted.

Trimbox helps Gmail users reduce unwanted mail by finding mailing lists and older messages, then offering tools to unsubscribe, delete, and block future messages. Users can unsubscribe from a list with one action; if the list requires a formal request, Trimbox can send one. To clear older mail, users can delete messages from a sender in one action. Those messages move to Trash and are permanently removed after 30 days. Trimbox can also create editable Gmail filters to block unwanted senders. The maker says email data stays on the user’s device and is never shared, and that Trimbox is verified by Google. The service needs access to a Gmail account to find mailing lists and delete old junk mail. Trimbox is available as an extension, in a browser for Gmail, and as a mobile app on Android and iOS. The App Store listing says users can connect unlimited email accounts, but the free plan covers the first 10 unsubscribes; a subscription unlocks unlimited unsubscribes. The listed free plan is free.
