Bilingual AI Newsletters: GPT-4o, Images, Videos for HubSpot & SharePoint

This n8n workflow enables marketing teams to generate professional bilingual newsletters effortlessly from a simple text prompt via webhook. GPT-4o drafts structured German and English content adhering to a JSON schema. It pulls an HTML template from SharePoint, injects the AI-generated copy using a Code node, and optionally creates visuals: high-res images via Pollinations AI (with overlays) and short videos with Lyria2 audio merged via FAL AI and FFmpeg.

After drafting, a Gmail approval step ensures quality control—only proceeding on approval. Final distribution intelligently routes based on user intent: emailing to HubSpot contact lists or saving HTML, images, and video URLs to SharePoint libraries. Ideal for growth teams shipping multilingual content without coding.

Benefits include massive time savings (hours to minutes), consistent branding via templates, scalable multi-channel output, and no-code customization. Use cases: weekly product updates, event recaps, or promotional campaigns targeting global audiences, integrating seamlessly with existing HubSpot and Microsoft 365 stacks.
