Cold DMs work, but what works better is DMing leads you've already chatted with like best buddies. This n8n workflow acts like the intern of your dreams and automates relationship building by monitoring when your prospects post, pinging fresh posts (last 2 hours), writing relevant comments you can customize, sending Slack notifications with post preview and suggested replies, and tracking what you've already commented on so you never double-tap accidentally. Get why you actually need this (and why manual stalking isn't scaling), step-by-step setup guide (15 minutes max), troubleshooting guide when things go sideways, and the JSON workflow. Built with free tools and APIs, this system costs absolutely nothing and turns prospects into warm leads before you ever send a DM.
