Email scraper

Hey guys I'm looking for some type of software that I can put a list of irks and it scrapes the email addresses from them. I tried doing it with scrapebox but wasn't too succesfull. Thanks in advance

If using scrape box load up targeted keywords lets say business owner, I do a custom footprint using "contact" as the target word and I scrape thousands of email addresses at a time with this method and they are targeted email addresses

how many emails will you need
