The agent extracts key metadata and insights from each message, including:\n\n* **From** – the sender’s email address\n* **To** – the recipient’s email address\n* **Subject** – the subject line of the email\n* **Summarize** – a concise summary of the email body generated by the AI\n\nOnce processed, the structured output is stored in a **database table**. This allows for easy indexing, reporting, and integration with other business systems.\n\nBy automating this process, the flow ensures consistent, searchable, and easily digestible information from diverse email sources significantly reducing manual review and improving workflow efficiency."
