Send a weekly summary with PostgreSQL

Runs on a schedule across PostgreSQL, Discord and Slack, runs the text through an AI chain, then rolls the rows up into a few numbers. Built for newsletters, around a "Gather from PostgreSQL" step, in 19 documented nodes.

Send a weekly summary with PostgreSQL and Discord 24/7. An original, ready-to-import n8n workflow built around the 'Scheduled Digest' pattern for marketing & advertising. It runs on a schedule and orchestrates 19 nodes across PostgreSQL, Discord, Slack. 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 PostgreSQL and Discord in step for newsletters, without anyone re-typing a row
  • A failed PostgreSQL or Discord call is retried rather than dropped, at any of the 19 nodes in this newsletters build
  • Branches rejoin before PostgreSQL, so a newsletters run reports once rather than 19 times
  • The newsletters AI step is isolated from PostgreSQL, so models swap without touching the other 19 nodes
  • Fans the same result out to Slack in the same run, for newsletters

Use cases

  • Teams keeping PostgreSQL and Discord aligned by hand for newsletters
  • Newsletters work where "Gather from PostgreSQL" is still a manual step before PostgreSQL
  • Newsletters work that only reaches PostgreSQL on a schedule, when someone remembers to start it

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Collecting from multiple sources and blending them into one stream
  • Rolling many rows up into a few reportable numbers
  • Summarizing and formatting a readable digest

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, Discord, Slack). 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.
