📝 Description This workflow helps automatically classify incoming emails using a combination of conditional logic and minimal AI-based classification. The system checks email content, performs sentiment analysis, uses OpenAI for categorization, and routes emails accordingly — with smart but efficient use of LLMs and AI Agents.

⚙️ How it works Trigger: An IMAP Email Trigger initiates the workflow upon receiving a new email.

Code Block: Parses essential data from the email.

Switch Node: Routes emails based on classification.

LLM Chain: Processes specific email cases (e.g., inquiries or complaints).

AI Agent (Minimal): Used only when other methods cannot determine intent.

Email Responses: Sends tailored replies or routes to support/sales teams accordingly.

Sentiment Analysis: Assists with tone evaluation for better response routing.

🧩 Set up steps Estimated setup time: 10–15 minutes

You’ll need:

An IMAP-compatible email account

OpenAI or any compatible LLM provider

Pinecone (optional, for vector memory)

SMTP credentials for sending email

Replace placeholder credentials in sticky notes before running.

Automated Email Classification and Response System with Groq AI and Pinecone

This n8n workflow automates the process of classifying incoming emails using AI, storing their content in a vector database, and potentially generating automated responses or actions based on their sentiment. It leverages Groq for fast AI processing and Pinecone for efficient vector storage and retrieval.

What it does

This workflow is designed to streamline email management by:

  1. Triggering on new emails: It listens for new emails arriving in a configured IMAP inbox.
  2. Extracting email content: It extracts the text content from the incoming email.
  3. Analyzing sentiment with AI: It uses a Groq-powered AI model to perform sentiment analysis on the email content.
  4. Classifying email content: It utilizes an AI Agent to classify the email based on its content, potentially identifying categories or topics.
  5. Storing email embeddings in Pinecone: It generates embeddings for the email content using Cohere and stores them in a Pinecone vector store for future similarity searches or context retrieval.
  6. Conditional processing: It includes a "Switch" node, implying conditional logic to route emails based on classification or sentiment (though the specific conditions are not defined in the provided JSON).
  7. Sending automated responses/actions: It has a "Send Email" node, indicating the capability to send automated email replies or notifications. It also includes an "X (Formerly Twitter)" node, suggesting potential for posting updates or alerts based on email content.

Prerequisites/Requirements

To use this workflow, you will need:

  • IMAP Email Account: Access to an IMAP server to trigger the workflow on new emails.
  • Groq API Key: For the Groq Chat Model and AI Agent to perform language model operations.
  • Cohere API Key: For generating embeddings.
  • Pinecone Account and API Key: To set up and interact with your Pinecone vector database.
  • SMTP Email Account: For sending automated email responses.
  • X (Formerly Twitter) Account (Optional): If you intend to post updates to X.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up an IMAP Email credential for the "Email Trigger (IMAP)" node.
    • Configure Groq credentials for the "Groq Chat Model" and "AI Agent" nodes.
    • Set up Cohere credentials for the "Embeddings Cohere" node.
    • Configure Pinecone credentials for the "Pinecone Vector Store" node.
    • Set up an SMTP Email credential for the "Send Email" node.
    • (Optional) Configure X (Formerly Twitter) credentials if you plan to use the "X" node.
  3. Customize Nodes:
    • Email Trigger (IMAP): Configure the IMAP server details, email address, and folder to monitor.
    • AI Agent: Customize the agent's prompt and tools to define how it classifies emails and what actions it can take.
    • Sentiment Analysis: Adjust any specific parameters for sentiment analysis if available.
    • Pinecone Vector Store: Configure your Pinecone index name and any other relevant settings.
    • Switch: Define the conditions for routing emails based on the output of the AI classification or sentiment analysis.
    • Send Email: Customize the recipient, subject, and body of the automated email responses.
    • X (Formerly Twitter): Configure the tweet content if used.
  4. Activate the Workflow: Once all credentials and node settings are configured, activate the workflow to start processing incoming emails automatically.

This workflow provides a robust foundation for building an intelligent email management system, capable of understanding, classifying, and responding to emails with the power of AI.

🎓 How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
