Cleanfox vs EmailSlim

Cleanfox is a free service for removing unwanted email and unsubscribing from newsletters. It identifies recurring senders and lets users decide what to keep before cleaning. For a newsletter, users can remove all its messages, delete received emails while staying subscribed, or keep it. Mail support includes Gmail, Outlook, Yahoo Mail, iCloud Mail, and most other providers. Card and list views help sort newsletters, with bulk actions in list view; users can add multiple mailboxes and sort them together. Automatic cleanup rules are available. An initial mailbox scan takes an average of 30 minutes to 3 hours. Deleted messages move to the mailbox trash and remain recoverable until the email provider empties it, typically after 5 to 30 days. Cleanfox says it uses end-to-end encryption, does not read or sell emails, and anonymizes newsletter and commercial-transaction data for market statistics. It says users are not targeted by advertising. Attachment downloading and deletion is marked “Soon.” Cleanfox is available on Android, iOS, and the web.

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.
