Receive a summary email every four hours from the address `quarantine@gcmconsultants.com` listing your quarantined messages. ![image001.png](https://docs.gcmconsultants.com/uploads/images/gallery/2026-06/wR9dB5bmqgq5An8y-embedded-image-srqft1l2.png) 2. Review the different sections in the email, which separate messages by security level (e.g., high-risk phishing). ![image002.png](https://docs.gcmconsultants.com/uploads/images/gallery/2026-06/JwqLGkpyABjkSzYp-embedded-image-m7nbt3yf.png) 3.
