Follow up: PostgreSQL & Gmail
Runs on a schedule across PostgreSQL, Gmail and Slack, routes each kind of record down its own branch, then runs the custom logic in a Code node. Built for auto-responders, around a "Normalize Email Payload" step, in 18 documented nodes.
Follow up with trial users with PostgreSQL and Gmail 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 18 nodes across PostgreSQL, Gmail, Slack. 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. The result is a hands-off process that just works.
Key benefits
- ✓Keeps PostgreSQL and Gmail in step for auto-responders, without anyone re-typing a row
- ✓A failed PostgreSQL or Gmail call is retried rather than dropped, at any of the 18 nodes in this auto-responders build
- ✓Branches rejoin before PostgreSQL, so a auto-responders run reports once rather than 18 times
- ✓Fans the same result out to Slack in the same run, for auto-responders
- ✓Pinned sample data ships with it — run all 18 nodes for auto-responders before wiring PostgreSQL
Use cases
- →Teams keeping PostgreSQL and Gmail aligned by hand for auto-responders
- →Auto-responders work where "Normalize Email Payload" is still a manual step before PostgreSQL
- →Auto-responders work that only reaches PostgreSQL on a schedule, 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.
- •Checking for conversion before every step so the drip stops
- •Segmenting the audience up front
- •Moving data between PostgreSQL, Slack and Gmail 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, Gmail, Slack). 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.
