Welcome to this comprehensive guide on creating an emailing AI agent using n8n. n8n is a powerful workflow automation platform that enables you to build sophisticated email processing systems powered by artificial intelligence. In this tutorial, we'll walk through the complete process of setting up an AI agent that can automatically read, analyze, and respond to emails intelligently.
Before we dive into building our AI email agent, let's ensure we have all the necessary prerequisites in place. First, you'll need a running n8n instance, which can be hosted locally or on a cloud platform. Second, you'll need an email account with API access, such as Gmail or Outlook, configured with proper authentication. Third, obtain an API key from an AI service provider like OpenAI or Anthropic. Finally, having a basic understanding of workflow automation concepts will help you follow along more effectively.
Now let's set up the email trigger node, which is the foundation of our AI email agent. First, create a new workflow in your n8n interface. Then, search for and add an email trigger node - you can choose from IMAP Email Trigger, Gmail Trigger, or Outlook Trigger depending on your email provider. Configure the node by adding your email credentials, specify the folder to monitor which is usually the INBOX, set how frequently n8n should check for new emails, and choose whether to mark emails as read after processing.
Next, we'll add the AI processing node that will analyze our emails. Search for and add an OpenAI or Anthropic node to your workflow. Configure the node by adding your AI service API credentials and setting the operation to Chat Completion. Create a system message that instructs the AI on how to process emails, such as summarizing content or drafting replies. Use expressions to pass the email data from the trigger node, like the subject, sender, and body text. Finally, configure model parameters such as temperature and max tokens to control the AI's response style and length.
Finally, let's test and activate our AI email agent. Connect all the nodes in your workflow by drawing lines between them. Use the Execute Workflow button to test the entire process - you can send a test email or use the manual trigger feature. Verify that emails are being processed correctly and the AI is generating appropriate responses. Check the quality of AI outputs and adjust prompts if needed. Once testing is successful, activate the workflow by toggling the switch in the top right corner. Your AI email agent is now live and will automatically process incoming emails according to your configuration.
