n8n RSS to PostNitro Carousel Drafts + Gmail Alerts

Turn new TechCrunch RSS articles into PostNitro carousel drafts—then get Gmail alerts

This n8n workflow watches the TechCrunch RSS feed for new items, generates PostNitro carousel content from each article URL, creates a scheduled PostNitro draft one day in advance (LinkedIn document format), and notifies you via Gmail—including error alerts if generation fails.

What this workflow does

• Polls every minute when new items appear in the TechCrunch RSS feed.
• Limits processing to the first 10 RSS items per run to keep throughput controlled.
• For each article, sends the article URL to PostNitro AI to generate a carousel design.
• Creates a PostNitro draft in DRAFT status for the generated design, scheduled for +1 day in the future using LinkedIn document settings.
• Sends a Gmail notification confirming each draft is ready for review.
• If PostNitro AI generation errors, sends a Gmail email including the error and the article link.

Use cases

• Content operations: draft LinkedIn carousel posts from trending TechCrunch headlines without manual sourcing.
• SaaS marketers: queue social creative drafts in PostNitro ahead of time and review on your schedule.
• Automation engineers: add a reliable RSS-to-draft pipeline with status and failure visibility via Gmail.

Technical details
