I am in the staffing and recruitment space and purchased this app to find emails. l started out with 20 leads and the system could not find not even ONE! l uploaded 600 plus - almost 700 leads and the system could not find not even ONE!! l contacted customer service via their platform chatbox and the lady told me "OUR DATABASE IS NOT ABLE TO FIND ANY OF THOSE LEADS EMAILS. We are NOT UP TO DATE YET"!!! l almost fainted! Your system boasts 100M records, emails and phone numbers and you cannot FIND ONE EMAIL OUT OF 700 leads????? THIS IS CRAZY!! Save your money and your time - look else where please! They refunded my money - thank GOD!
