n8n Auto Blog to LinkedIn Drafts (OpenAI + Gmail Storage)

Turn your blog into LinkedIn drafts—automatically

This n8n workflow reads your blog’s RSS feed every morning, uses OpenAI to write LinkedIn post drafts in your brand voice, and stores each draft as a Gmail draft for quick human review.

What this workflow does

• Executes daily at 8:00 AM on a schedule.
• Loads your settings: Uses configuration values such as RSS feed URL, brand voice guidelines, lookBackHours, and maxPostsPerRun.
• Reads your blog RSS feed: Fetches the latest items from the configured RSS feed.
• Filters by recency & limits volume: Includes only posts published within the lookback period, and restricts output to maximum posts per run.
• Generates LinkedIn drafts with OpenAI: For each selected post, sends the post’s title, link, and snippet to OpenAI to create a LinkedIn update draft (up to 120 words) matching your brand voice.
• Creates Gmail drafts for review: Saves each generated LinkedIn draft as a Gmail draft email so you can approve and publish manually.

Use cases

• SaaS marketing teams: Automatically convert new product/blog updates into consistent LinkedIn content without starting from scratch.
• Founder-led content: Draft posts from recent articles while maintaining a specific voice and tone.
• Automation engineers: Use it as a practical pattern for RSS → OpenAI generation → Gmail draft review inside n8n.

Technical details

• Nodes/stack used: set, rss feed read, filter, limit, gmail, sticky note.
• Integrations: OpenAI for draft generation and Gmail (OAuth) to create draft emails in the selected mailbox.
• Key workflow controls: lookBackHours and maxPostsPerRun to manage which RSS items become LinkedIn drafts.

Setup note: Configure the RSS feed URL, brand voice guidelines, lookBackHours, and maxPostsPerRun, then add an OpenAI credential and a Gmail OAuth credential to enable draft creation.
