The business model looks great, they say you can access demographic leads, export, file and get email address to any lead for a low monthly price!! Unlimited!! But when signed up for the service and tried to use it, the filters wouldn't work right and I wasn't getting hardly any leads. The filters defaulted to areas I did not pick. The leads that I did get did not have working email addresses. They were dummy addresses ([email protected]). So I tried to contact Salesfully, sent in a ticket, emailed the support dept, responded to their email to me, posted on their facebook page. Still NO response. Nothing! I finally cancelled my automatic payment to them off paypal. They got me for the first $28. Servies me right to get sucked in to a scam like this. If it looks too good to be true, it must not be!! Under no circumstances should you sign up with this company.
