Build a weekly summary with PostgreSQL
Runs on a schedule across PostgreSQL, Slack and Google Sheets, drops anything it has already handled, then rolls the rows up into a few numbers. Built for inbox triage, around a "Gather from PostgreSQL" step, in 24 documented nodes.
Build a weekly summary with PostgreSQL and Slack hands-free. An original, ready-to-import n8n workflow built around the 'Scheduled Digest' pattern for marketing & advertising. It runs on a schedule and orchestrates 24 nodes across PostgreSQL, Slack, Google Sheets. 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 PostgreSQL and Slack in step for inbox triage, without anyone re-typing a row
- ✓Safe to re-run: records already in PostgreSQL or Slack are skipped, across all 24 nodes of this inbox-triage build
- ✓A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 24 nodes in this inbox-triage build
- ✓Every inbox-triage run leaves an audit row behind, alongside PostgreSQL
- ✓Fans the same result out to Google Sheets in the same run, for inbox triage
Use cases
- →Teams keeping PostgreSQL and Slack aligned by hand for inbox triage
- →Inbox triage work where "Gather from PostgreSQL" is still a manual step before PostgreSQL
- →Inbox triage work that only reaches PostgreSQL on a schedule, when someone remembers to start it
Integrations
Workflow preview (24 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
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.
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.
- •Collecting from multiple sources and blending them into one stream
- •Rolling many rows up into a few reportable numbers
- •Archiving each run for an audit trail
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 (PostgreSQL, Slack, Google Sheets, 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.
