Lucas Walter breaks down four practical n8n automation agents he built for marketing that are actively generating thousands of dollars in revenue. Instead of theory, this video shows the actual workflows --- from lead capture and qualification to personalized outreach and follow-up sequencing --- all running inside n8n without writing code. Lucas explains how each agent connects to real tools, why the automations compound over time, and where most people get stuck when building their first marketing workflows. If you've been curious about AI-powered marketing automation but don't know where to start, this walkthrough gives you battle-tested templates and a free download link so you can clone, customize, and run them yourself. The video covers the architecture decisions behind each agent, common failure points to watch for, and how to think about automation as a force multiplier rather than a replacement for human judgment.
