One of my clients wanted to learn how to better handle customer feedback in their restaurant. The challenge was clear: they needed a simple way to collect responses, store them properly, and reply with personalized emails without adding extra manual work.
For this tutorial project, I walked them through building an automated workflow in n8n. We set up a form submission trigger, organized the data with Google Sheets, and applied rules to separate feedback based on satisfaction. Then we connected OpenAI to generate thoughtful email bodies and subjects, while ensuring the output was clean and readable by converting HTML to text before sending it through Gmail.
The whole setup gave my client a clear, hands-on understanding of how automation can save time while still keeping customer communication personal. The result was not just a working system, but also the confidence to manage and adapt it on their own.
