I go step by step to show how I build an AI agent from scratch using N8N. This is my simple way to automate email replies with AI, without writing any code. I walk you through how N8N works, how to self-host it with Hostinger to save money and keep your data private, and how to set up AI models like OpenAI inside your workflows.

I also show how to use triggers, nodes, and even add memory and tools to make your automation smarter. This helps me handle support emails faster and lets me set up agents that do way more than just reply. Everything is explained clearly, and you’ll see how to test, fix errors, and add new steps like sending urgent messages to your team.
