Description

Turn appointment requests in your inbox into booked time without long back and forth. The system watches Gmail for unread messages, checks for meeting intent, and replies with clear time options from your Google Calendar. It fits teams that handle demos, client calls, hiring screens, or service bookings.

Here is how it works. Gmail checks for new unread emails every minute. A language model reads the subject and snippet to decide if the message is asking to schedule a meeting; other messages get ignored by design. If it is a request, an agent looks at your Google Calendar for the next month, finds open time slots, and writes a friendly reply that suggests exact times. The reply is sent in the same thread and the email is marked as read to keep your inbox organized.

Setup is simple. Connect Gmail, Google Calendar, and OpenAI, then select the correct calendar and adjust the date window to match your work hours. Expect to cut manual scheduling from many minutes per email to seconds and convert more requests to confirmed times. This helps solo operators, sales reps, coordinators, and admin teams stay on top of inbound scheduling without adding headcount.

How to set this up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with Gmail, Google Calendar and OpenAI. See the Tools Required section above for links to create accounts with these services.
  3. Open the Gmail Trigger node. In the credential field, click Create new credential and follow the on screen steps to connect your Gmail account. Allow read, send, and modify mail permissions.
  4. In the Gmail Trigger node, keep the unread filter and every minute polling, or adjust the schedule to match your needs. Save the node.
  5. Open the OpenAI Chat Model nodes. In the credential field, click Create new credential, paste your OpenAI API key from your OpenAI account API page, and save. Keep the model as gpt 4o mini or choose another available model.
  6. Open the Google Calendar node. Click Create new credential, connect your Google account, and grant calendar permissions. Select the correct calendar from the drop down instead of the placeholder value.
  7. Confirm the Agent node is connected to the Google Calendar tool. The tool connection should show one calendar tool linked to the agent.
  8. Review the Agent system message. Update tone, working hours, and meeting length so the reply fits your style and availability policy.
  9. Adjust the time window in the Google Calendar node if needed. For example, extend timeMax to two months or narrow it to a few weeks.
  10. Activate the workflow. Send a test email to your Gmail with a subject like Can we meet tomorrow and a short request. Wait for the next poll and confirm a reply is sent in the same thread and the original email is marked as read.
  11. If no reply arrives, open the n8n execution view. Check that the classifier labeled the message as an appointment, verify the Agent produced text, and confirm Gmail credentials have send permission.

Automate Gmail Inbox Triage and Draft Replies
Busy inboxes slow teams down. This build reads each new Gmail message, sorts it into a clear label, and writes a polite draft reply you can review. Ideal for office staff, sales assistants, and school admin teams that need fast triage without missing urgent notes. You get a clean queue and a ready to edit answer for each thread. New emails are pulled from Gmail every minute. The text goes to an AI classifier powered by Google Gemini, which picks a category like High Priority, Work Related, or Promotion. Based on that choice, the flow adds the matching Gmail label automatically. At the same time, an AI Agent using a Groq model creates a first draft reply and saves it as a Gmail draft, so a human can edit and send. It uses separate models for classification and drafting to improve accuracy and tone, and you can add more categories as your workload grows. Setup only needs Gmail labels and API access for Google Gemini and Groq. Expect faster first responses, clearer priorities, and less inbox stress, often saving 30 to 60 minutes each day. No code changes are needed beyond choosing labels and pasting API keys. Great for sorting inquiries, vendor emails, and parent or client messages while keeping control over final sends.

Automate Gmail Inbox Organization
Keep your inbox tidy without manual sorting. This setup scans new Gmail messages and puts them into the right labels using AI. It helps teams that get many emails and want quick triage and clear folders. A Gmail trigger checks for new mail every five minutes. A short wait controls timing. The agent uses an OpenAI chat model with memory to review the message, compare it with your existing Gmail labels, and choose the best match. If nothing fits, it creates a new label and then applies it to the email. It reads all labels, fetches the message by id, creates labels when needed, and adds labels back to Gmail. Results are consistent because the memory keeps short context for each thread. You only need Gmail access and an OpenAI key. Connect both credentials in n8n Cloud, keep the default poll time, and test by sending a sample email with a clear subject. Expect faster inbox cleanup, fewer missed messages, and a clear label structure for shared mailboxes. Many teams use it for marketing leads, vendor requests, or project updates. Time saved adds up fast, and you can handle more email volume without extra staff.

Organize Gmail with AI Labeling and Auto Filing
Keep your Gmail tidy without manual sorting. The system reads each new email and files it into the right label or creates a clear new one. Great for teams that want a clean inbox and faster follow up. It starts when Gmail checks for new messages every five minutes. An AI agent reviews the subject, sender, and content, then uses Gmail tools to read labels, fetch the message, add labels, or create a label when none fit. Low value mail can have the Inbox label removed, while normal and important mail stays visible. New labels follow your naming style and are placed as sublabels under an AI parent when needed. A short memory window keeps context per message so the agent makes consistent choices. The model can handle long emails with a large token limit, and a brief wait helps space out calls. Connect a Gmail account and add your OpenAI key to run it. Set the poll time and review the rules in the system message. Expect strong time savings and a steady folder structure across the team. This is useful for promotions, vendor mail, project updates, and resumes, and can be tuned with a few simple edits.
