What it is
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.
