valid email addresses harvested from a list I'll give you. Objective: outreach to sell books. You might use the stack you are most comfortable with Python + BeautifulSoup, Scrapy, Selenium, Node.js + Puppeteer, or similar 'as long as the final data is clean and deduplicated' Deliverables: • A CSV file containing each email address alongside the exact page URL where it was found • A brief note on the toolchain or script used (for reproducibility) Accuracy matters more than sheer volume Do Not give me a bloated list full of bounces.. I only neeed proper clean verified and contactable info.
