In their own words
ClearInbox
ClearInbox is a web email-cleanup app that can also be self-hosted with Docker. It groups messages into smart folders such as newsletters, social, shopping, finance, travel, old mail, and large mail, then suggests archiving or deletion. Mailing lists can be unsubscribed individually or in bulk where RFC 8058 one-click support exists. Auto Clean rules move, archive, delete, star, or mute messages on schedules or when new mail arrives. A sender screener holds first-time senders for approval or rejection, and users can block senders or domains. The web client supports composing, replying, forwarding, searching, labeling, starring, and pinning across multiple connected accounts. Supported providers include Gmail, Outlook, Microsoft 365, Yahoo Mail, iCloud Mail, AOL, Fastmail, Exchange, and IMAP services. The maker says cleaning uses headers and metadata, full bodies are not stored, and connections are encrypted.
