True one-click unsubscribe
RFC 8058 one-click, unsubscribe links, and mailto — Spam Squirrel picks the strongest method each sender supports and executes it for real.
Human escalation
No unsubscribe link? We find a real contact at the sender's domain and forward a CAN-SPAM/GDPR removal request from your own mailbox.
Repeat-offender reporting
Senders who ignore your unsubscribe get flagged with evidence — forward it to the FTC's official spam-report address in one click.
Safe contacts allowlist
Protect the senders you love. Allowlisted addresses and domains are never touched, never flagged, never lost.
Proof, not promises
Every action is logged with the sender's server response code — a full audit trail of every unsubscribe you've ever run.
Privacy-first by design
We read headers, not your email. Mail bodies never leave your Microsoft 365 mailbox, and your data is never sold.
