In my carrier, I have used many email extracting tools but nothing is as effective as Email Extract Online. It has really made my work easy. I would say the accuracy of this tool is more than 95%. Would rate it 10/10

Email extract saved my hours of time looking for valid email addresses by crawling different websites, and extracting the data I needed. The best thing is - this is one of the extractors that look ups in bulk sans experiencing IP restrictions. I have used it and been using, you should try it once!
