The workflow is triggered for each new email which gets passed to an AI classification agent. It assigns the email to one of the categories defined in the prompt (Customer Support, Sales opportunity, Promo, Personal,...). The agent also determines whether a reply is needed and if it is important. 2. If a reply is needed, we ask the AI Email Writer to draft a response. Even if it is missing context it can help us draft an outline for the response. 3. The email draft is sent to gotoHuman where the reviewer can manually edit it or ask to regenerate it with the option to even edit the prompt (Retries loop back to the AI Email Writer node) 4. Approved email replies are automatically sent from the workflow How to set up 1. Most importantly, install the gotoHuman node before importing this template!
