Overview
This workflow collects user preferences via a web form (categories and email), scrapes MediaMarkt’s offers page through Bright Data, uses GPT-4o-mini to generate a filtered JSON list of recommended deals, formats those deals into an HTML email, and then sends the personalized deals to the user. Finally, it displays a confirmation page showing how many deals were sent.
