Who’s it for

Marketing, growth, and automation teams that need to ship polished bilingual newsletters—complete with images, optional video, and multi-channel distribution—without writing a line of code.

How it works / What it does

  1. A Webhook receives a plain-language request (e.g. “Create a newsletter about XYZ and store it in SharePoint”). The Webhook can be changed to another trigger, fr example Manual Trigger.
  2. An AI Agent (OpenAI GPT-4o) drafts German & English newsletter copy following a strict JSON schema.
  3. SharePoint fetches an HTML template; a Code node injects AI copy into the placeholders.
  4. Optional creative assets:
    • Pollinations AI → image (resolution check & frame overlay)
    • FAL AI → short video + Lyria2 audio → merged via FFmpeg API
  5. A Gmail Approval step sends the draft to an approver; the flow continues only on “Approve”.
  6. Depending on user intent the workflow:
    • Emails the newsletter to HubSpot contacts, and/or
    • Saves HTML (+ JPG/Video URL) to a SharePoint library.

How to set up

  1. Import the template
  2. Open the yellow sticky note and follow the checklist
    • Create credentials for OpenAI, HubSpot (App Token), Microsoft 365, Gmail, and FAL AI.
    • Enter them in n8n Credential Manager (never in the HTTP node).
  3. Edit the Configuration Settings Set node with your ENV_* variables.
  4. Activate the workflow, copy the production Webhook URL, and trigger it with JSON body { "text": "…" } or with a desired trigger.

Requirements

  • OpenAI account
  • Microsoft 365 tenant (SharePoint & Outlook)
  • HubSpot App Token
  • FAL AI API Key (video & audio generation)

How to customize

  • Want a different language? Tweak the AI prompt inside AI Agent.
  • Want a different storage provider? Change the SharePoint nodes to Google Drive or Dropbox.
  • Skip video generation: set include_video to false in the incoming prompt.
  • Change the distribution logic by adjusting the WF Result Switch node.
  • Add more channels (e.g. Slack) by inserting additional branches after the Switch and modifying the intent determination at the beginning of the workflow.

n8n Workflow: Basic Workflow Template

This n8n workflow serves as a foundational template, demonstrating a simple flow with various core n8n nodes for data manipulation, conditional logic, and external API interaction. It's designed to be a starting point for building more complex automations.

What it does

This workflow showcases several fundamental n8n capabilities:

  1. Receives a Webhook Trigger: Initiates the workflow upon receiving an HTTP request to its unique webhook URL.
  2. Performs an HTTP Request: Executes an arbitrary HTTP request, demonstrating interaction with external APIs.
  3. Applies Conditional Logic (If): Routes data based on a true/false condition, allowing for branching paths in the workflow.
  4. Applies Conditional Logic (Switch): Routes data based on multiple possible conditions, providing more complex branching.
  5. Merges Data: Combines data from different branches back into a single stream.
  6. Edits Fields (Set): Modifies, adds, or removes fields from the incoming data.
  7. Loops Over Items (Split in Batches): Processes items in batches, useful for handling large datasets or rate limits.
  8. Waits for a Duration: Pauses the workflow for a specified amount of time.
  9. Interacts with AI Agents (Langchain): Includes an AI Agent node, suggesting integration with AI models for complex tasks.
  10. Interacts with OpenAI Chat Model: Specifically includes an OpenAI Chat Model node, indicating potential for generating text or engaging in conversational AI.
  11. Converts to File: Transforms data into a file format.
  12. Extracts from File: Extracts data from a file.
  13. Interacts with HubSpot: Connects to HubSpot for CRM-related actions.
  14. Sends Emails (Gmail & Microsoft Outlook): Demonstrates sending emails via both Gmail and Microsoft Outlook.
  15. Executes Custom Code: Allows for custom JavaScript logic to be run within the workflow.
  16. Interacts with Microsoft SharePoint: Connects to Microsoft SharePoint for document or list management.

Prerequisites/Requirements

To use this workflow effectively, you will need:

  • n8n instance: A running n8n instance (cloud or self-hosted).
  • Webhook: The n8n Webhook node will generate a unique URL when activated.
  • HubSpot Account: If you intend to use the HubSpot node, you'll need a HubSpot account and appropriate credentials configured in n8n.
  • Gmail Account: If you intend to use the Gmail node, you'll need a Gmail account and appropriate credentials configured in n8n (typically OAuth).
  • Microsoft Outlook Account: If you intend to use the Microsoft Outlook node, you'll need a Microsoft account with Outlook and appropriate credentials configured in n8n (typically OAuth).
  • OpenAI API Key: If you intend to use the OpenAI Chat Model or AI Agent nodes, you'll need an OpenAI API key.
  • Microsoft SharePoint Account: If you intend to use the Microsoft SharePoint node, you'll need a SharePoint account and appropriate credentials configured in n8n.
  • External API Endpoints: For the HTTP Request node, you'll need an external API endpoint to interact with.

    • Click on each node and configure the necessary credentials. You may need to create new credentials in n8n if you haven't already.
  3. Configure Webhook:
    • The "Webhook" node will automatically generate a unique URL. Use this URL to trigger the workflow from an external application or service.
  4. Configure Other Nodes:
    • Review each node's settings (e.g., the URL for the "HTTP Request" node, conditions for "If" and "Switch", fields for "Edit Fields").
    • Adjust them according to your specific use case.
  5. Activate the Workflow:
    • Once configured, click the "Activate" toggle in the top right corner of the n8n editor to enable the workflow.
  6. Test the Workflow:
    • Trigger the webhook (e.g., by sending a POST request to its URL) or manually execute the workflow to test its functionality.

This template provides a robust starting point for developing custom n8n automations, showcasing a wide range of core functionalities.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
