# AI-powered auto-reply detection for email

Email AI Agents can now detect auto-reply messages that lack standard email headers, preventing reply loops that previously went undetected.

## What's new

Previously, auto-reply detection relied solely on email headers (`Auto-Submitted`, `X-Autoreply`, `Precedence`). Emails without these headers — such as some out-of-office replies, delivery confirmations, and automated messages — could trigger repeated AI Agent responses.

The AI Agent now uses AI-powered detection to identify auto-replies regardless of whether standard headers are present. When an auto-reply is detected:

* The AI Agent stops responding to the conversation
* The conversation closes through the standard 72-hour inactivity window
* Auto-reply messages remain visible in the Conversations View — a "Conversation Resolution Analysis" event in the Coaching UI shows the detection result
* CSAT surveys are not sent for these conversations
* Webhook events continue to fire normally

Reply loops are now typically resolved within a few messages. No configuration is required.
