Description

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.
