| Privacy | The README says GMClean fetches email headers only and does not download email bodies. | The maker says email does not go to its servers and that its backend sees only plan and usage counts, never email. |
| Purpose | GMClean scans email headers, classifies messages, and supports mass unsubscribe, bulk deletion, and export. | Sender Sweep helps users see which senders fill their Outlook inbox, then bulk-delete, archive, or unsubscribe. |
| Unsubscribe | It supports one-click unsubscribe with RFC 8058 List-Unsubscribe-Post support and bulk unsubscribe. | Newsletters are detected automatically, and the app pulls an unsubscribe link from message headers. |

In their own words
GMClean
GMClean is a free, self-hosted web tool for scanning email headers, classifying messages, unsubscribing in bulk, deleting email, and exporting data. It works with Gmail, Outlook, and custom IMAP mailboxes, with up to 10 mailboxes connected at once. GMClean fetches headers such as sender, subject, and List-Unsubscribe details without downloading message bodies. It can scan INBOX, Spam, Promotions, Trash, and other IMAP folders. Inbox analysis includes a 0–100 health score based on five weighted factors, sender insights, and email age distribution. Classification uses heuristic rules, with optional Gemini assistance for ambiguous cases. Users can unsubscribe with one click using RFC 8058 support or unsubscribe in bulk; bulk deletion runs in batches of 500 messages. Exports include selected subscriptions with resubscribe links and scanned emails in CSV format. The project documents deployment with npm, Docker, or Docker Compose. It says app data stays in browser IndexedDB and there is no cloud database or telemetry. Credentials are encrypted with AES-256-CBC before storage, and setup requires an ENCRYPTION_SECRET. The repository is MIT-licensed.
