Does unsubscribing remove all personal data?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
Unsubscribing stops future emails but doesn't trigger data deletion. These are separate rights. Think of unsubscribe as pausing communication while your record remains on file; data deletion (right to erasure) requires a distinct request.
You must keep unsubscribe records to prevent re-emailing that person. This suppression list is legally necessary and permitted even under strict privacy laws. Deleting all data would actually harm compliance by losing the unsubscribe record.
If someone wants full data deletion, they must specifically request it. Then you delete everything except the suppression entry (email hash or identifier) that prevents future contact. Explain this distinction in your privacy policy to set expectations.
