Follow up: PostgreSQL, scheduled
Runs on a schedule across PostgreSQL, Slack and Twilio, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for newsletters, around a "Stamp & Shape Email" step, in 19 documented nodes.
Follow up with leads with PostgreSQL and Twilio with instant alerts. An original, ready-to-import n8n workflow built around the 'Drip Sequence' pattern for marketing & advertising. It runs on a schedule and orchestrates 19 nodes across PostgreSQL, Slack, Twilio. 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 Slack in step for newsletters, without anyone re-typing a row
- ✓A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 19 nodes in this newsletters build
- ✓The pause before PostgreSQL is durable — a newsletters run survives a restart
- ✓Fans the same result out to Twilio in the same run, for newsletters
- ✓Pinned sample data ships with it — run all 19 nodes for newsletters before wiring PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Slack aligned by hand for newsletters
- →Newsletters sequences that run over days and must survive a restart before PostgreSQL
- →Newsletters work where "Stamp & Shape Email" is still a manual step before PostgreSQL
- →Newsletters work that only reaches PostgreSQL on a schedule, when someone remembers to start it
Integrations
Workflow preview (19 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (19 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.
- •Sequencing multi-day sends with durable Wait nodes
- •Checking for conversion before every step so the drip stops
- •Segmenting the audience up front
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, Twilio). 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.
