Auto-post the content calendar: Slack for blog posts, scheduled
Runs on a schedule across Slack, Google Sheets and Notion, walks the list in batches, pausing between them, then drops anything it has already handled. Built for blog posts, around a "Read Content Calendar (Google Sheets)" step, in 31 documented nodes.
Auto-post the content calendar with PostgreSQL and Slack and log the results. An original, ready-to-import n8n workflow built around the 'Social Scheduler' pattern for content creation & media. It runs on a schedule and orchestrates 31 nodes across Slack, Google Sheets, Notion. 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 Slack and Google Sheets in step for blog posts, 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 blog-posts build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this blog-posts build
- ✓The pause before Slack is durable — a blog-posts run survives a restart
- ✓Batches the work so Slack rate limits never break a blog-posts run
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for blog posts
- →Blog posts sequences that run over days and must survive a restart before Slack
- →A backlog too large to push into Slack in one pass, across 31 nodes
- →Blog posts work where "Read Content Calendar (Google Sheets)" is still a manual step before Slack

What's inside (31 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
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
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Reading a content calendar and publishing only what is due
- •Spacing posts with a batch loop and Wait to respect rate limits
- •Walking a list in batches instead of firing everything at once
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, Notion, PostgreSQL, …). 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.
