Domain Email Scraping Required

I will supply a list of website domains and need you to pull every publicly-available general contact email you can find for each one. The count of domains may vary—sometimes a handful, other times a far longer list—so the script or method you use must scale without manual tweaks.

What I expect back is a single, well-structured Excel spreadsheet. Each row should include the domain, the email address, and (if you can capture it) the source URL where that address was found so I can verify authenticity.

Only general contact addresses are relevant; please skip sales, support, or other role-specific inboxes unless they clearly serve as the site’s main contact. De-duplicate results across domains, and make sure any scraping complies with the target site’s publicly exposed data and applicable regulations.

If you already have a reliable scraping stack—Python with BeautifulSoup or Scrapy, an API-based solution, etc.—let me know, but the key thing is accuracy and completeness, not the underlying tool.
