Re-engage open deals: Slack & PostgreSQL
Runs on a schedule across Slack and PostgreSQL, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for follow-ups, around a "Keep Valid Contacts" step, in 13 documented nodes.
Re-engage open deals with PostgreSQL and Slack. An original, ready-to-import n8n workflow built around the 'Reminders & Follow-ups' pattern for sales & CRM. It runs on a schedule and orchestrates 13 nodes across Slack, PostgreSQL. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. The result is a hands-off process that just works.
Key benefits
- ✓Keeps Slack and PostgreSQL in step for follow-ups, without anyone re-typing a row
- ✓A failed Slack or PostgreSQL call is retried rather than dropped, at any of the 13 nodes in this follow-ups build
- ✓The pause before Slack is durable — a follow-ups run survives a restart
- ✓Pinned sample data ships with it — run all 13 nodes for follow-ups before wiring Slack
- ✓13 nodes, each with a doc card explaining what it does for follow-ups
Use cases
- →Teams keeping Slack and PostgreSQL aligned by hand for follow-ups
- →Follow-ups sequences that run over days and must survive a restart before Slack
- →Follow-ups work where "Keep Valid Contacts" is still a manual step before Slack
- →Follow-ups work that only reaches Slack on a schedule, when someone remembers to start it
Integrations

What's inside (13 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
Core levelA compact production shape: validation and error handling without extra machinery.
- •Scheduling time-based follow-ups that survive restarts
- •Exiting the sequence when the task is already done
- •Moving data between Slack 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). 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.
