AI-Powered Lead Email Classification & Auto-Reply with GPT-4o and Gmail

How it works This workflow automatically responds to incoming emails identified as potential leads using AI-generated text.
It connects to your email inbox via IMAP, classifies incoming messages with an AI model, filters out non-leads, and sends a personalized reply to relevant messages.

Steps Email Trigger (IMAP): Watches your inbox for new emails in real time. Is Lead? (Message Model): Uses AI to determine whether the sender is a lead. Filter: Passes only lead emails to the next step. Write Customized Reply (Message Model): Generates a personalized response using AI. Get Message: Retrieves original email details to ensure correct threading. Reply to Message: Sends the AI-generated reply to the sender.

Setup Instructions Connect your IMAP Email credentials to the first node and set the folder to watch (e.g., INBOX). In the "Filter leads" node, adjust the AI prompt to match your lead qualification criteria. In the "Reply with customized message" node, edit the AI prompt to reflect your product, service, or business tone. Connect your Gmail (or other email provider) credentials in the Get Message and Reply to Message nodes. Test with a few sample emails before activating.

Requirements IMAP-enabled email account (for receiving messages) Gmail API access (or modify to your email provider) OpenAI or other AI model credentials for message analysis and reply generation
