Follow up: Slack & PostgreSQL
Runs on a schedule across Slack, PostgreSQL and Google Sheets, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for auto-responders, around a "Normalize Email Payload" step, in 22 documented nodes.
Follow up with subscribers with PostgreSQL and Slack on autopilot. An original, ready-to-import n8n workflow built around the 'Drip Sequence' pattern for marketing & advertising. It runs on a schedule and orchestrates 22 nodes across Slack, PostgreSQL, 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 Slack and PostgreSQL in step for auto-responders, without anyone re-typing a row
- ✓A failed Slack or PostgreSQL call is retried rather than dropped, at any of the 22 nodes in this auto-responders build
- ✓The pause before Slack is durable — a auto-responders run survives a restart
- ✓Every auto-responders run leaves an audit row behind, alongside Slack
- ✓Fans the same result out to Google Sheets in the same run, for auto-responders
Use cases
- →Teams keeping Slack and PostgreSQL aligned by hand for auto-responders
- →Auto-responders sequences that run over days and must survive a restart before Slack
- →Auto-responders work where "Normalize Email Payload" is still a manual step before Slack
- →Auto-responders work that only reaches Slack on a schedule, when someone remembers to start it
Integrations
Workflow preview (22 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (22 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.
- •Sequencing multi-day sends with durable Wait nodes
- •Checking for conversion before every step so the drip stops
- •Moving data between Slack, Google Sheets and PostgreSQL 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, PostgreSQL, 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.
