# Keep email logs lean

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Required
- Chapter: [Email privacy](https://agentwranglers.se/playbook/email/email-privacy)
- Rule: Log what you need to run and debug email, without full message bodies, and delete it on a set schedule.
- How: Log the message ID, template, time, status and recipient domain. Leave out bodies, sign-in links and reset tokens. Hash or shorten full addresses where you can. Delete sent messages and delivery logs after a fixed period, such as 30 days, and say so in the privacy policy. Keep personal data out of all logs, as in [logs without personal data](https://agentwranglers.se/playbook/operations/logs/logs-without-personal-data), and follow [log retention](https://agentwranglers.se/playbook/operations/logs/log-retention).
- Check: Search the logs for a test recipient's full address, the message body and a reset link. None of them appears, and records older than the set period are gone.
