Re-engage upcoming appointments: Slack & Google Sheets, scheduled
Runs on a schedule across Slack, Google Sheets and PostgreSQL, pauses on a Wait node until it is time to continue, then branches on the check before anything is written. Built for drip campaigns, around a "Segment Audience" step, in 21 documented nodes.
Re-engage upcoming appointments with PostgreSQL and Telegram for your team. An original, ready-to-import n8n workflow built around the 'Reminders & Follow-ups' pattern for marketing & advertising. It runs on a schedule and orchestrates 21 nodes across Slack, Google Sheets, PostgreSQL. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.
Key benefits
- ✓Keeps Slack and Google Sheets in step for drip campaigns, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 21 nodes of this drip-campaigns build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 21 nodes in this drip-campaigns build
- ✓Bad input stops the run for drip campaigns instead of landing in Slack
- ✓The pause before Slack is durable — a drip-campaigns run survives a restart
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for drip campaigns
- →Drip campaigns sequences that run over days and must survive a restart before Slack
- →Drip campaigns work where "Segment Audience" is still a manual step before Slack
- →Drip campaigns work that only reaches Slack on a schedule, when someone remembers to start it

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.

What you'll learn
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Scheduling time-based follow-ups that survive restarts
- •Computing due dates and windows from timestamps
- •Exiting the sequence when the task is already done
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, Google Sheets, PostgreSQL, Telegram). 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.
