The LinkedIn Signal Machine
A comment is not noise. It's a signal. This playbook and its n8n workflow turn the people who comment on LinkedIn posts into a short, qualified list every morning, and open the conversation with their own words.
- 11 pages
- n8n workflow included
- November 2026
In this playbook you will:
- Collect the people who engage with the posts you track, without duplicates
- Keep only decision makers, and write a first line from their own comment
- Send them to a lemlist sequence and get a summary before your first coffee
Six steps, from the first comment to a live campaign
The playbook walks you through the workflow node by node, with the credentials to connect, the settings to fill, the prompt rules, a starter sequence, a go-live checklist and the rules to respect.

The trigger, the steps in order, the tools you need and the moment a human approves. Read it once, then build it.
