Email scraping tools basically work by crawling through web pages and identifying patterns that match email formats, like something@domain.com. They use algorithms to scan HTML code or text content for these patterns. Some advanced tools even use AI to improve accuracy.
But yeah, not all websites allow scraping. Some have anti-scraping measures like CAPTCHAs or IP blocking. As for legality, it depends on where you are and how you use the data. Always check the website's terms of service and local laws.
If you're looking for tools, I’ve used Hunter.io and Scrapy before. Hunter is more user-friendly, while Scrapy is great if you’re into coding. Just be careful not to spam people—nobody likes that!
