SalesQL is the first tool I find for finding personal email. It is the best one I ever see.
Accurate most of the time and find 99% of emails. I suggest all the recruiters use it. Review collected by and hosted on G2.com.
For a free one its good. Not used the paid one and am not sure about the pricing. I am palling to take a paid version in the next few months and check how this will work. Review collected by and hosted on G2.com.
