I need a clean, well-structured database of business emails taken exclusively from the German directory www.wlw.de (Wer liefert was). For every record, please capture two fields exactly as they appear on the site: • Company Name • Corresponding business Email Address Only genuine business-domain emails are useful here; personal or educational addresses can be skipped outright. Please extract the data with whatever method you trust—Python, BeautifulSoup, Selenium, or another crawler—so long as the final list is accurate and free of duplicates. A quick manual sweep or API-based validation to remove bounced or malformed addresses will be appreciated. Deliverables 1. One CSV or Excel file containing the two columns: Company Name | Email Address 2. A brief note on your scraping process, total rows delivered, and any validation steps you applied. Acceptance criteria • Data source is solely wlw.de • Each email is paired with its company name • Duplicate rows removed • At least 95 % of addresses pass a standard email-validation check Happy to clarify categories, quantity targets, or any site-specific issues once you are ready to begin.
