Clean Email vs EmailSlim

Clean Email helps people manage busy inboxes by grouping messages for bulk organization, archiving or removal. Its Unsubscriber lists subscriptions and newsletters for bulk unsubscribing, while Auto Clean rules can move, star, mark, delete or archive messages according to criteria such as sender, domain, status and age. Screener holds messages from unknown senders for review, where users can allow or block them. The service connects directly to mailboxes from Gmail, Yahoo, AOL, iCloud, Outlook and other IMAP providers, so it can work alongside an existing email app. Apps are listed for Android, iOS, macOS and the web. Clean Email says its index stores message metadata, not message bodies or attachments by default; it deletes the index after 45 days without a login or when an account is removed. A free account cleans up to 1,000 messages, but excludes Screener, Sender and Mailing List Settings, and Auto Clean. The pricing note lists paid plans from $9.99/mo and a 14-day trial; premium plan prices are not itemized here.

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.
