Generate newsletters: Slack for editing
Runs on a schedule across Slack, Google Sheets and MySQL, runs the text through an AI chain, then reads the feed and keeps only what is new. Built for editing, around a "Read Source Feed" step, in 31 documented nodes.
Generate newsletters with MySQL and Slack hands-free. An original, ready-to-import n8n workflow built around the 'Content Generation' pattern for content creation & media. It runs on a schedule and orchestrates 31 nodes across Slack, Google Sheets, MySQL. 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. Your team sees the right data at the right time.
Key benefits
- ✓Keeps Slack and Google Sheets in step for editing, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 31 nodes of this editing build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this editing build
- ✓Every editing run leaves an audit row behind, alongside Slack
- ✓The editing AI step is isolated from Slack, so models swap without touching the other 31 nodes
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for editing
- →Editing work where "Read Source Feed" is still a manual step before Slack
- →Editing work that only reaches Slack on a schedule, when someone remembers to start it

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.

- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •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 Slack, Google Sheets and MySQL 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 (Slack, Google Sheets, MySQL, 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.
