Reply to specific email thread
The agent sends a reply to an existing email conversation, maintaining proper threading headers (In-Reply-To and References) automatically, allowing for seamless communication.
How it works
Changes data in your accountsCustomer support
The agent first uses list_messages or search_email to find the relevant email thread and identifies the thread_id. It then calls reply_to_email with the appropriate message content. The agent must ensure the correct inbox is used and that the reply is contextually appropriate based on the thread history.
