ClearInbox vs EmailSlim

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.

EmailSlim is a web service for finding storage-heavy messages in Gmail and Microsoft email accounts and cleaning them up. It analyzes metadata rather than email body content, ranking senders and domains by the total storage their messages use. Users can inspect grouped senders and approve bulk deletions; messages first move to Trash or Deleted Items. One-click unsubscribe uses standard List-Unsubscribe headers when available, though it may not work for every sender. Supported accounts include Gmail, Outlook, Hotmail, Live.com, MSN, and Microsoft 365. Connections use Google OAuth or Microsoft OAuth, and access can be revoked in account settings. EmailSlim says operations require explicit user consent and initiation. It describes encryption in transit and at rest, access controls, and regular security audits. The free scan costs nothing and covers the first 500 emails without a credit card or subscription. Paid pricing is from $2.50/mo. One-time, annual, and monthly automation plans use mailbox tiers up to 150k emails, with exact amounts shown after sign-in. Monthly automation is described as daily inbox cleanup.
