PROJECT OVERVIEW
The AI Newsletter Automation - Industry Insights solution enables founders, agencies, and marketing teams to publish high-quality weekly newsletters without manual research or writing.
Built using n8n, this automation discovers trending news, plans structured newsletter sections using AI agents, writes polished content, formats it into clean HTML, and prepares a ready-to-review draft inside Gmail.
The entire workflow runs automatically on a predefined schedule, turning weekly industry updates into a professional newsletter in minutes.
OBJECTIVES
The Challenge
Before automation, newsletter creation required:
This process consumed 4–6 hours per week, limiting consistency and scalability.
A solution was required to fully automate research, writing, editing, and formatting, while maintaining editorial quality.
THE SOLUTION ARCHITECTURE (HOW DOES IT WORK?)
The automation workflow is built entirely inside n8n and the system transforms raw
weekly news into a ready-to-send newsletter automatically.
How does it work?
Step 1: Scheduled Workflow Trigger
A Schedule Trigger node runs automatically every week at a predefined time.
This ensures:
100% consistent newsletter creation
No missed publishing cycles
No manual initiation required
Step 2: Data Context Generation
A Date & Time node generates the current formatted date, which is injected into the newsletter introduction.
This ensures every issue feels current and contextually relevant.
Step 3: Smart News Discovery
A Tavily Search node retrieves relevant articles from the past week based on a predefined topic (e.g., AI Automation for Small Businesses).
The search pulls:
Recent news articles
Source URLs
Raw article summaries
This eliminates manual browsing and ensures up-to-date content sourcing.
Step 4: Newsletter Planning (AI Agent)
An AI agent powered by LangChain analyzes the collected articles and:
Generates a compelling newsletter title
Identifies exactly three core topics
Structures the overall newsletter outline
A structured output parser ensures clean, predictable formatting for downstream steps.
Step 5: Topic-Level Research
Each identified topic is independently researched using additional Tavily searches.
This ensures:
Supporting references
Multiple credible sources
Better insight depth
Fact-backed writing
Step 6: Section Writing (AI Agent)
A section writer AI agent generates one polished section per topic using Cohere for natural language generation.
Each section includes:
Clear, professional tone
Business-focused insights
Inline clickable citations
Structured paragraphs
This ensures readability and authority.
Step 7: Content Aggregation
An Aggregate node combines all generated sections into a single structured dataset.
This prepares the content for final editing and formatting.
Step 8: Final Editing & HTML Formatting
A response editor AI agent:
Writes a cohesive introduction
Adds a professional conclusion
Improves clarity and logical flow
Formats the entire newsletter in email-safe HTML
Generates a subject line (≤ 80 characters)
The result is a fully structured, visually clean newsletter.
Step 9: Gmail Draft Creation
A lightweight JavaScript node extracts:
Subject line
HTML body
The Gmail node then creates a draft email, ready for review or scheduling.
No manual copy-pasting required.
