Produce newsletters with Google Sheets
Runs on a schedule across Google Sheets and Slack, hands the decision to an AI agent with its own tools, then branches on the check before anything is written. Built for captions, around a "Stamp & Shape Draft" step, in 24 documented nodes.
Produce newsletters with Google Sheets and Slack end to end. An original, ready-to-import n8n workflow built around the 'Content Generation' pattern for content creation & media. It runs on a schedule and orchestrates 24 nodes across Google Sheets, Slack, HTTP / REST API. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. What used to take a morning now runs on its own.
Key benefits
- ✓Keeps Google Sheets and Slack in step for captions, without anyone re-typing a row
- ✓A failed Google Sheets or Slack call is retried rather than dropped, at any of the 24 nodes in this captions build
- ✓Every captions run leaves an audit row behind, alongside Google Sheets
- ✓The captions AI step is isolated from Google Sheets, so models swap without touching the other 24 nodes
- ✓Pinned sample data ships with it — run all 24 nodes for captions before wiring Google Sheets
Use cases
- →Teams keeping Google Sheets and Slack aligned by hand for captions
- →Captions work that needs a judgement call per item before it reaches Google Sheets
- →Captions work where "Stamp & Shape Draft" is still a manual step before Google Sheets
- →Captions work that only reaches Google Sheets on a schedule, when someone remembers to start it

What's inside (24 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
Agent tools included (2)
An AI Agent is only as capable as the tools wired into it. These are read from the template's own graph — every one is a real node in the file you download.
- Draft Specialist (Sub-workflow) · Another n8n workflow
- Research Specialist (Sub-workflow) · Another n8n workflow
This agent runs without conversation memory - each run starts from the incoming request.
From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Chaining a writer pass and a separate critic pass for better output
- •Publishing as a draft so a human stays the final gate
- •Moving data between Google Sheets and Slack in a single run
Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.
Common questions
What exactly do I get?
The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.
How do I import it into n8n?
In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.
Do I need anything else for it to work?
You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Google Sheets, Slack, HTTP / REST API). No coding is required.
What if it doesn't work for me?
If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.
Can I modify or resell it?
You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
