How I built a 5-channel AI Newsletter Agent in n8n (And solved a 1,800+ item backlog)

Hey everyone! 🤖

I just finished an n8n workflow that completely automates my morning tech and business news scanning. It pulls from 5 channels, picks the top 5 breakthroughs, and drops a premium, custom-branded newsletter straight to my inbox every midnight.

Here is the exact setup and a major scaling issue I solved:

🧱 The Flow:

Schedule Trigger ➡️ 5 Parallel RSS Nodes ➡️ Merge (Append) ➡️ JS Code Node ➡️ AI Agent ➡️ Gmail (HTML).

🚨 The Problem:

When I first merged all 5 streams, it spat out 1,865 raw articles. Passing that straight to an LLM would instantly blow past context limits or cost a fortune.

⚡ The Fix:

I added a simple JS Code Node right before the AI Agent. It strips out all the raw HTML metadata, extracts just the title, summary, and sourceUrl, and uses a .slice(0, 30) script to hand over only the 30 freshest headlines.

🧠 The Result:

The AI Agent filters those 30 down to the top 5 entrepreneur-focused stories, formats them with clean inline HTML links, and drops them into a beautiful, mobile-responsive "Card Layout" template inside the Gmail node under my brand, Automedops.

No more scrolling through noise. Just a high-yield, 2-minute intelligence brief waiting for me every morning. ☕
