Smart Email Responder Workflow Using AI

This n8n workflow automates the process of responding to incoming emails using AI, intelligently classifying email content, generating responses, and even scheduling follow-up events if necessary. It helps streamline communication and improve productivity by handling routine email tasks.

What it does

1. Monitors Incoming Emails: The workflow is triggered by new emails received in your Gmail inbox.
2. Classifies Email Content: It uses an AI-powered Text Classifier to categorize the content of each incoming email.
3. Generates AI Response: Based on the email's content, a Google Gemini Chat Model generates a relevant and appropriate email response.
4. Conditional Logic for Follow-up:
   • If the AI-generated response indicates a need for a follow-up meeting or event, it proceeds to schedule a Google Calendar event.
   • Otherwise, it directly sends the AI-generated response via email.
5. Sends Email Response: The workflow sends the AI-generated response to the original sender.
6. Schedules Google Calendar Events (Optional): If the email classification or AI response suggests a meeting, it creates an event in your Google Calendar.
7. Loops for Multiple Emails: It can process multiple incoming emails in batches, ensuring all new emails are handled.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Gmail Account: Configured as a credential in n8n for both triggering on new emails and sending replies.
• Google Calendar Account: Configured as a credential in n8n for scheduling events.
• Google Gemini API Key: For the Google Gemini Chat Model to generate AI responses.
• Langchain Integration: Ensure the @n8n/n8n-nodes-langchain package is installed in your n8n instance for the Text Classifier and Google Gemini Chat Model nodes.

Setup/Usage

1. Import the Workflow:
   • Download the provided JSON file.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
2. Configure Credentials:
   • Locate the "Gmail Trigger", "Gmail", and "Google Calendar" nodes.
   • For each, click on the "Credential" field and select or create new Google OAuth2 credentials that grant access to your Gmail and Google Calendar.
   • For the "Google Gemini Chat Model" node, configure your Google Gemini API key.
3. Configure AI Nodes:
   • Text Classifier: You may need to train or configure the Text Classifier with specific labels and examples relevant to the types of emails you want to classify (e.g., "meeting request", "support inquiry", "general").
   • Google Gemini Chat Model: Review the prompt configuration to ensure the AI generates responses in your desired tone and style.
4. Activate the Workflow:
   • Once all credentials and configurations are set, click the "Activate" toggle in the top right corner of the workflow editor to enable it.

The workflow will now automatically monitor your Gmail inbox and respond to emails based on its AI capabilities.
