What this workflow does
-
Pulls free security/tech headlines from multiple RSS feeds (eg, CISA, BleepingComputer, Krebs, SecurityWeek, Ars Technica, TechCrunch, Hacker News).
-
De-duplicates stories, keeps only the last 24 hours, and limits to a manageable number.
-
Uses OpenAI to write a concise brief with sections and "Why it matters."
-
Sends a clean HTML email via Gmail.
Category: Security / News
Time to set up: ~10--15 minutes
Difficulty: Beginner--Intermediate
Cost: Mostly free (OpenAI tokens + Gmail)
What you'll need
- n8n (recent version)
- OpenAI credentials
- Gmail (or SMTP) credentials
- A few free RSS feed URLs (swap in/out as you like)
Setup steps
- Trigger -- Add a Cron to run daily (pick your time and timezone).
- Fetch -- Add one RSS Read node per source and connect all to a Merge (append).
- De-duplicate (this run) -- Add Remove Duplicates and compare on a stable key (prefer the article URL).
- Freshness -- Add an IF to pass only items published in the last 24 hours.
- Limit -- Add Limit to cap the total items (eg, 25).
- Summarize -- Add OpenAI → Message a model to produce a JSON brief with subject + HTML body.
- Email -- Add Gmail → Send to deliver the brief to your inbox.
Tips & Troubleshooting
- If everything gets discarded at de-dup and while testing, switch to "within current input" or reset the node's stored values.
- If no items pass the IF, widen the date window temporarily (some feeds publish late).
- If the email arrives blank, ensure Gmail email type is set to HTML and the subject/body fields map to the model's output.
