Summarize long emails: Slack & PostgreSQL, webhook
Fires the moment a webhook arrives across Slack, PostgreSQL and Microsoft Teams, scores the sentiment of every message, then runs the custom logic in a Code node. Built for newsletters, around a "Normalize Email Payload" step, in 18 documented nodes.
Summarize long emails with PostgreSQL and Microsoft Teams at scale. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for marketing & advertising. It fires on a webhook and orchestrates 18 nodes across Slack, PostgreSQL, Microsoft Teams. 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. Nothing slips through the cracks.
Key benefits
- ✓Keeps Slack and PostgreSQL in step for newsletters, without anyone re-typing a row
- ✓A failed Slack or PostgreSQL call is retried rather than dropped, at any of the 18 nodes in this newsletters build
- ✓Branches rejoin before Slack, so a newsletters run reports once rather than 18 times
- ✓Every newsletters run leaves an audit row behind, alongside Slack
- ✓Fans the same result out to Microsoft Teams in the same run, for newsletters
Use cases
- →Teams keeping Slack and PostgreSQL aligned by hand for newsletters
- →Pushing newsletters events into Slack and PostgreSQL the moment they land, not on the next poll
- →Newsletters work where "Normalize Email Payload" is still a manual step before Slack
- →Newsletters work that only reaches Slack when a webhook arrives, when someone remembers to start it
Integrations
Workflow preview (18 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (18 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
Advanced levelAdds branching depth and audit logging on top of the core pattern.
- •Rejoining parallel branches with Merge so the run reports once
- •Moving data between Slack, PostgreSQL and Microsoft Teams in a single run
- •Splitting one run into branches and merging the results back
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, PostgreSQL, Microsoft Teams). 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.
