Unsubscribed
Done, immediately. Your address is marked unsubscribed and no further issues will be sent to it.
The record is kept only so a later signup cannot quietly re-add you by accident. Nothing about you is retained beyond the address and that flag, and you can ask for it to be deleted outright by opening an issue.
The writing does not go away: the same digest is published at /weekly and in the feed, with no address required.
