EmailSlim vs Paperweight

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.

Paperweight is a desktop app that scans email to map accounts, mailing lists, and personal data, then helps users clean up and prepare data access or deletion requests. It builds a company inventory from messages such as receipts, sign-up confirmations, password resets, and security alerts. The app identifies mailing lists for unsubscribe requests and detects personal details in past messages, including addresses, payment cards, IBANs, and national identifiers. It supports Gmail, Outlook, Apple/iCloud, standard IMAP accounts, and Proton Mail through Proton Bridge. Analysis and database storage happen locally; the maker says its servers do not receive email content or credentials. Published under the MIT license, the app lets users inspect or build its code. Free includes one email account with full-history sync and overview features. Pro costs $60 a year, billed yearly, and adds cleanup actions, multiple accounts, privacy requests, and MCP access. Requests are prepared for user review, not sent automatically. Paperweight focuses on relationships found in the inbox and does not remove data-broker records.
