# Email, notifications and AI

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

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-22.

> Write every email part in the recipient's language, tell AI models which language to answer in, and test AI quality in each language you support.
