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. Learn more about [automatic reply handling](/docs/channels/email/email-onboarding).
