Bought MLM leads are still not going to be laydown sales, you WILL still need to talk to them, qualify them and move them along in the process. When you receive the email that you have a new lead in, call them and ask them how you can help, if they are nasty or negative, just get off the phone. Never, whether you bought the lead or not, try to convert someone who is nasty or negative, it just is not worth your time.
A great example of this is going on appointments with people to share the business opportunity with their friends and family. Most of them will be unable to express what the business is about, and they will have never given a presentation on the business before. As you know, family and friends tend to ignore opportunities that we present to them. They still regard as as the same old family member, or the same old friend. But by bringing a third party, and allowing this person to provide the presentation for them, it allows the potential members to open up, listen, and potentially sign up.
