What EmailSlim is
EmailSlim analyzes email metadata to help people identify storage-heavy senders and clean up Gmail or Microsoft email accounts. It ranks senders and domains by the storage their messages use, letting users review the biggest contributors first. Users can inspect grouped senders and choose bulk deletion, but each deletion requires their approval. One-click unsubscribe is available through standard List-Unsubscribe headers when a sender supports them. The service connects through Google OAuth or Microsoft OAuth and supports Gmail, Outlook, Hotmail, Live.com, MSN, and Microsoft 365. EmailSlim says it processes sender, subject line, date, size, and labels, but does not read message bodies. Users can revoke access through account settings, and deleted messages first go to Trash or Deleted Items. The service says it uses encryption in transit and at rest, access controls, and regular security audits. Its free scan covers the first 500 emails at no cost, with no credit card or subscription. Paid pricing is From $2.50/mo. One-time cleanup, annual subscription, and monthly automation plans use mailbox tiers, with exact amounts shown after sign-in; monthly automation is described as daily inbox cleanup.
