Back to case studies
AI Agent Workflow - Newsletter Curator
Curated weekly newsletters in minutes, not days
Use case
Manual newsletter creation had become a time-intensive, low-stakes drain, taking hours, sometimes days, to compile. While valuable for brand consistency and authority, the process didn’t justify the effort.
“We wanted an AI agent workflow that could generate a newsletter in minutes, and reclaim a week of lost productivity.”
The challenge
Manually curating and formatting articles each week
Low-stakes content, but high time commitment
Repetitive tasks not worth human effort
Required styling for website, LinkedIn, and email output
The solution
Ancast Intelligence developed a fully autonomous AI Agent Workflow using n8n, enabling rapid newsletter generation and delivery.
Toolchain used:
n8n for orchestration and workflow logic
Claude / GPT-4 Turbo for content generation
OpenAI APIs for token control and prompt engineering
DALL·E for image generation
Gmail API for direct delivery
Google Drive & Sheets for asset management
Features
8+ RSS/API integrations (broadcast, AI, tech sources)
LLM scoring logic to filter quality content (min score: 7/10)
Only surfaces fresh articles from the past 7 days
HTML formatting with gradients, stylized sections, and Read More links
Auto-generated images from article summaries
Email-ready output with fallback logic if image gen fails
Triggered on schedule (e.g., Thursdays at 7am)
QA-ready: human-in-the-loop review before publishing
Timeline
Agent workflow build: 3 days
Testing & tuning: 2 days
Phase 2: Image generation & final styling: 3 days
Total: 1 week to rollout
