Automate LinkedIn Carousel Drafts from RSS with PostNitro & Gmail

Turn RSS articles into LinkedIn carousel drafts automatically—every minute

This n8n workflow polls the TechCrunch RSS feed, uses PostNitro AI to generate a LinkedIn carousel design from each new article URL, then saves it as a LinkedIn draft scheduled for the next day. You’ll receive a Gmail notification with a review link—or an error alert if generation fails.

What this workflow does

• Monitors TechCrunch RSS by polling the RSS feed every minute.
• Processes one article per cycle (limits processing to one article per poll cycle).
• Sends the article URL to PostNitro AI to generate a LinkedIn carousel design.
• If successful, creates a PostNitro scheduled post in DRAFT status for LinkedIn and schedules it for one day later.
• Emails a Gmail success message with the draft details and a review link.
• If generation fails, sends a Gmail error alert that includes the error information and the article URL.

Use cases

• SaaS marketing teams who want consistent LinkedIn carousel content sourced from a reliable tech news feed.
• Automation engineers building repeatable content pipelines with n8n + PostNitro AI.
• Operators who prefer a human review step before publishing (drafts are created for the next day).
• Content producers who want faster turnaround from RSS discovery to social-ready drafts.
