I have been using mail hunter for about 4 years now, it has helped me connect with thousands of people from all over world that are interested in my products or services which is very important to us as an E-commerce business owner who sells online courses via our website www.teacherspayTeachers". It's not always 100% sure but when we do get results they're usually great (we've gotten many leads just by checking out competitors websites). Sometimes you will receive fake accounts where someone else uses your account details without permission like their names etc., this can be frustrating if there isn't any way around them contacting other users through "report" button - however sometimes these reports actually help others identify suspicious activity going forward e..g getting scammed/hacked into giving up personal information such credit card numbers ect...I am able reach hundreds at once within seconds making sales easier than ever before compared to previous methods used previously i would say.
