How to Scrape Emails From Facebook

ProxyCrawl’s Leads API is by far the best and easiest way to new leads. The best part about it is it won’t repeat any leads that you have already done. This ensures that any email you get will be new and applicable for your use. Leads API takes out all the hard work for you, giving you an easy and enjoyable experience.
I have tested it. Hope this will help you in your business.
