Basically, this node lies in wait inside your inbox, and as soon as a new message arrives… *bam*, your workflow fires up.\n\n### Step 1: Connect Your Gmail Account\n- In n8n, add a **Gmail Trigger** node.  \n- Click **Credential to connect with** and select your Gmail account.  \n- If you haven’t done it yet, click **Add new**, connect your Google account, and allow access.  \nPro tip: don’t worry, it won’t read your personal emails to gossip — everything stays inside your workflow.  \n\n### Step 2: Basic Settings\n- **Poll Times**: select `Every Minute`.  \n   → This way, n8n checks your inbox every minute.  \n- **Mode**: `Message Received`.  \n   → You want the flow to trigger whenever a customer writes to you.  \n- **Event**: `Message Received`.  \n   → Same logic, keep it simple.  \n- **Simplify**: turn it off (`OFF`).  \n   → Why? Because if you enable \"Simplify,\" you only get a stripped-down version of the email. And you want it all: subject, sender, raw message… the full package.  \n\n### Step 3: Expected Output\nWhen you execute the node, you should see:  \n- **id**: unique identifier of the email.  \n- **threadId**: conversation identifier (super useful to reply in the same thread).  \n- **snippet**: a short preview of the email (first lines).  \n- **From**: your customer’s email address.  \n- **To**: your email address.  \n- **Subject**: the subject of the email.  \n- **payload**: the full body of the email (yep, in base64 — but we’ll handle that later).  \n\nAnd that’s it — your Gmail Trigger is set up. In short, the moment a customer writes “Hey, I have an issue with my account,” your workflow kicks in instantly (well, almost — it checks every minute).  \n"

You respond to technical requests, quotes, and customer questions. Your replies must be short, clear, friendly, and precise.”*  \n- **Chat Model** → connect your AI model (e.g. OpenAI GPT-4.1 Mini).  \n- **Memory (optional but recommended)** → connect a **Conversation Memory** node.  \n  → This allows the AI to retain conversation history and better understand follow-ups.  \n\n---\n\n### Expected Output\nWhen you run this node, you should see in the output:  \n- A field `output` containing the automatically generated AI reply.  \n- The text should be short, natural, and adapted to the customer’s tone (casual or formal).  \n\n👉 With the Gmail Trigger you capture emails, and with the AI Agent you get a reply ready to send — as if you had written it yourself.  \n"
