This n8n workflow template automates the process of collecting and delivering the "Top Deals of the Day" from MediaMarkt, tailored to user preferences. By combining user-submitted forms, Bright Data web scraping, GPT-4o-mini deal generation, and email delivery, this workflow sends personalized product recommendations straight to a user’s inbox.

Note: This workflow uses community nodes (Bright Data and Document Generator) which only work on self-hosted n8n instances.

What It Does

- Collects user preferences via a form (categories + email)

- Scrapes MediaMarkt’s deals page using Bright Data

- Uses GPT-4o-mini (OpenAI) to recommend top deals

- Generates a structured HTML email using a template

- Sends the personalized deals directly via email

Community Node Integration

We created and used the following community nodes:

- Bright Data, To scrape MediaMarkt deals using proxy-based scraping

- Document Generator, To generate a templated HTML document from deal data

These nodes are not available in n8n Cloud and require self-hosted n8n.

Step-by-Step Setup

4. Design Your HTML Template

5. Test the Workflow

Submit the form with test data and check that the entire flow, from scraping to email, executes as expected.
