# Inbound mail and replies

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.

> Read the mail that comes back. Accept postmaster and abuse reports, check who sent each reply before you act on it, and never answer an automatic reply.
