Automate email processing with AI-generated responses & approval

This AI-powered email processing automation aims to streamline the handling of incoming emails. It automatically summarizes email content using natural language processing, generates suggested responses, and routes them for manual approval before sending.

The workflow is triggered by new emails received via an IMAP integration, processes the email text, and leverages AI models to produce draft replies. These responses are then submitted to a human reviewer through a Gmail integration, who can approve or request edits before the finalized message is sent back to the original sender. This automation helps organizations provide timely, personalized, and professional email communication while maintaining human oversight over the process.
