Extract Emails from eCom, Publisher, Blog and Event URLs

I have a shortlist of eCom, Publisher, Blog and Event URLs I need every customer-facing email address that sits inside their HTML, even if it never appears as visible text on the page. This is a one-off job for now, not an ongoing crawl, so speed and accuracy matter more than scheduling or automation.

When you’re done, send me either:
• a tidy CSV or XLSX containing the email addresses and the page they were found on, or
• the script you used plus its output, so I can rerun it later if needed.

Let me know your approach and estimated turnaround; I’m ready to assign this right away.
