I’ve been building something over the last few weeks and wanted to share it because I’m curious if others are solving this the same way.
Most “GTM automation setups” I see (Zapier, Make, basic n8n flows) look fine on the surface… but they usually break the moment you try to run them in anything close to production.
So I ended up rebuilding mine from scratch in n8n as a full revenue pipeline system, not just a workflow.
What I built
1. Lead pipeline (end-to-end)
A simple lead doesn’t just get “captured” anymore.
It goes through:
Webhook → normalize → validate → enrich (Clearbit) → score → HubSpot → Postgres → Slack
So every lead is:
-
cleaned before entering the system
-
enriched with context
-
scored for intent
-
stored properly
-
and instantly visible to sales
2. Conversion tracking (real attribution)
When a deal closes or a conversion happens:
-
it gets sent to Google Ads
-
it gets sent to Meta
-
and the team gets notified in Slack
The goal here was simple: stop guessing where revenue actually comes from.
3. Dead Letter Queue (DLQ)
This was a big one for me.
Instead of losing bad data or broken leads:
-
everything invalid gets captured
-
stored with the raw payload
-
and logged with an error reason
-
plus a Slack alert so it’s visible immediately
Nothing silently disappears anymore.
4. Global error handling
If any workflow fails anywhere in the system:
-
it gets caught globally
-
logged with workflow name + error message
-
and sent to Slack
So debugging isn’t “hunt and pray” anymore.
What changed for me
The biggest shift wasn’t adding complexity.
It was treating GTM like infrastructure instead of automation.
Things like:
-
observability
-
failure handling
-
clean data flow
-
and traceability end-to-end
made way more difference than any “AI feature” I could’ve added.
Curious what others think
Has anyone here built something similar?
Especially around:
-
structuring multi-workflow n8n systems
-
handling DLQs properly
-
or doing attribution without everything becoming messy over time
Would be interested to compare approaches.
