# Unsubscribe

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Email](https://agentwranglers.se/playbook/email.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

> Let people leave with one click, honour it within two days, keep the link working and never pass on who left. Label each list so mail apps can manage it.
