Paperweight
Locally scans your inbox to find old accounts, real mailing lists and exposed personal data.
Paperweight reads your email history on your own machine — Gmail, Outlook, Proton Mail or any IMAP account — to reconstruct old accounts from signup and receipt emails, find real mailing lists worth unsubscribing from, and locate exposed personal data like phone numbers and payment details so you can request deletion. It's open source under MIT and runs 100% locally: no Paperweight servers see your mail. Free covers one account with full-history discovery and local curation; Pro ($5/month billed yearly, or a $25 30-day pass) adds actually sending unsubscribes and deletion requests across multiple accounts. It's also honest about a real limit: don't unsubscribe from unknown spam, since that just confirms your address is active.
What holds up
- +Runs 100% locally with no Paperweight servers — inbox data never leaves your computer
- +Open source under MIT, so the scanning and deletion-request logic is auditable, not just promised
- +Tells you not to unsubscribe from unknown spam senders, since that confirms your address is live
Mind the limits
- −Free tier only discovers — sending unsubscribes and deletion requests needs the $5/month Pro plan
- −Supports Gmail, Outlook, Proton (via Bridge) and plain IMAP only — no other proprietary providers
