Custom Deal Recommendations by Email Using Forms, Bright Data & GPT-4 Mini

 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-4-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](https://get.brightdata.com/ar8wlq0xkpv5) - Uses GPT-4-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](https://www.npmjs.com/package/n8n-nodes-brightdata)** - to scrape MediaMarkt deals using proxy-based scraping - **[Document Generator](https://www.npmjs.com/package/n8n-nodes-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 1. **Install Community Nodes** Make sure you're on a self-hosted n8n instance. Install: - `n8n-nodes-brightdata` - `n8n-nodes-document-generator` 2. **Configure Credentials** - **Bright Data API Key** (Proxy + Scraping setup) - **OpenAI API Key** (GPT-4-mini access) - **SMTP Credentials** for sending emails 3. **Customize the Form** Adapt the form node to collect desired categories and email addresses. Typical categories include appliances, phones, laptops, etc. 4. **Design Your HTML Template** In the Document Generator node, you can tweak the HTML/CSS to change how deals appear in the final email. 5. **Test the Workflow** Submit the form with test data and check that the entire flow—from scraping to email—executes as expected. --- ### How It Works: Workflow Overview 1. **User Interaction via Form** Users select product categories and enter their email. This triggers the workflow. 2. **Data Extraction via Bright Data** Bright Data scrapes the [MediaMarkt offers page](https://www.mediamarkt.es/es/campaign/campanas-y-ofertas) and returns HTML content. 3. **HTML Parsing** Key elements like product names, prices, and links are extracted for processing. 4. **GPT-4-mini Recommendation Generation** The extracted data is sent to OpenAI (GPT-4-mini), which filters, ranks, and enhances deals based on the user's preferences. 5. **Data Structuring & Split** The result is split into individual deal items to be formatted. 6. **HTML Document Creation** Document Generator populates a clean HTML template with the top recommended deals. 7. **Email Delivery** The final document is emailed via SMTP to the user with a friendly message. --- ### Final Output Users receive a **custom HTML email** featuring a curated list of top MediaMarkt deals based on their selected categories. --- ### Credentials Used - **Bright Data API** - Web scraping with proxy support - **OpenAI API** - Generating personalized recommendations - **SMTP** - Sending personalized deal emails --- ### Customization Tips - **Change the Data Source**: You can adapt this to scrape other e-commerce sites. - **Update the Email Template**: Make it match your branding or include images. - **Extend the Form**: Add preferences like price range or specific brands. - **Add Scheduling**: Use Cron to run the workflow daily or weekly. --- ### Questions?
