Weekly RSS Newsletter Digest in n8n with OpenAI + Kit

Turn your RSS feeds into a polished weekly newsletter—automatically

This n8n workflow runs every Monday at 05:00, pulls the latest stories from your chosen RSS/Atom feeds, uses OpenAI Chat Completions to generate clean grouped HTML, and then saves it as a Kit (ConvertKit) draft broadcast—with optional Slack and Gmail delivery for manual publishing.

What this workflow does

• Scheduled digest: Triggers every Monday at 05:00 via a scheduled trigger.
• Fetch RSS items: Reads recent items from your configured RSS/Atom feed URLs.
• Curate the newsletter: Keeps only stories from the last 7 days, removes duplicates, cleans snippets, and limits the digest to up to 25 items.
• Generate newsletter copy: Builds an OpenAI prompt from the curated items and calls the OpenAI Chat Completions API to draft well-structured HTML.
• Email-safe formatting: Wraps the generated HTML in an email-friendly container, sets the subject, and prepares preview text.
• Create a Kit draft: Sends the result as a draft broadcast in Kit (ConvertKit).
• Optional notifications & delivery: Posts a “draft ready” message to Slack (via Incoming Webhook) and/or emails the draft HTML via Gmail.

Use cases

• SaaS operators who want a consistent weekly update without manually copying links.
• Automation engineers building content pipelines from RSS into a newsletter workflow.
• Creators who want OpenAI-written summaries grouped into a ready-to-publish HTML digest.
• Teams that prefer reviewing drafts in ConvertKit/Kit before going live.
