Genesys Cloud provides email threading functionality that automatically groups related customer communications based on subject lines while filtering out reply and forward tags (Re and Fwd). By default, the system threads emails received within 30 days of the original message, with the timing period beginning after agent disconnection. Administrators can customize threading behavior through Admin > Contact Center > Email > Organization Email Settings, enabling them to reduce the threading window to a minimum or disable threading entirely by setting the period to zero days. The "Enable Subject Based Threading" option creates new conversation IDs when subject lines change, establishing separate conversations rather than extending existing threads. Threading continues indefinitely for undisconnected emails regardless of configured settings. When the configured time period expires agent disconnection or when customers initiate new emails with different subject lines, threading terminates and new conversations commence. The email threading timeline governs when Genesys Cloud sends initial survey invitations for email interactions when configured through the "As per the Threading Timeline" option in web survey policies, though this setting does not influence survey reminder timing. This configuration ensures agents receive complete email thread history for customer replies, providing necessary context for managing ongoing communications.
