Automates email processing, response generation with RAG, and requires manual approval before sending.

About This Workflow

This workflow automates the processing of incoming emails via IMAP. It summarizes the email content using an LLM, retrieves relevant information from a Qdrant vector database using RAG, and generates a draft response. The draft email is then sent via Gmail, requiring manual approval (Yes/No) through a 'Send and wait for response' mechanism before the final reply is sent.

Key Features

Email Trigger: Reads incoming emails using IMAP.
Content Summarization: Condenses email content for LLMs.
RAG Implementation: Leverages Qdrant vector store for knowledge retrieval.
AI-driven Response Generation: Crafts professional email replies.
Approval Workflow: Requires manual confirmation before sending replies.
Dual Language Capability: Designed to generate structured metadata in both English and Chinese.

How To Use

Configure Email Trigger: Set up the IMAP node to connect to your email account and fetch new emails.
Email to Markdown: Convert the incoming email's HTML content to Markdown for better LLM processing.
Summarize Email: Use the Email Summarization Chain to create a concise summary of the email content.
Set Email Variable: Store the summarized content using the Set Email node.
Generate Response: The Write email agent, using the OpenAI LLM and Qdrant Vector Store (via Embeddings OpenAI), will generate a draft response based on the email summary and your knowledge base.
Send for Approval: The Send Draft node (Gmail) sends an email with the drafted response and an approval link.
Approve or Reject: The Approve? node checks the approval status from the Gmail response.
Send Final Email: If approved, the Send Email node sends the final reply. If rejected, the workflow terminates or can be routed differently.
