Follow up with PostgreSQL & Slack
Runs on a schedule across PostgreSQL, Slack and Google Sheets, walks the list in batches, pausing between them, then branches on the check before anything is written. Built for auto-responders, around a "Read Pending Queue (PostgreSQL)" step, in 22 documented nodes.
Follow up with subscribers with PostgreSQL and Slack and log the results. 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 PostgreSQL, Slack, HTTP / REST API. 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 auto-responders, without anyone re-typing a row
- ✓A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 22 nodes in this auto-responders build
- ✓The pause before PostgreSQL is durable — a auto-responders run survives a restart
- ✓Batches the work so PostgreSQL rate limits never break a auto-responders run
- ✓Every auto-responders run leaves an audit row behind, alongside PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Slack aligned by hand for auto-responders
- →Auto-responders sequences that run over days and must survive a restart before PostgreSQL
- →A backlog too large to push into PostgreSQL in one pass, across 22 nodes
- →Auto-responders work where "Read Pending Queue (PostgreSQL)" is still a manual step before PostgreSQL
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 PostgreSQL, Google Sheets and Slack 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 (PostgreSQL, Slack, HTTP / REST API, Google Sheets). 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.
