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.
The reason I started Apache Leads way back in 2003 was that I was a Diamond level distributor for a San Diego based MLM company and had quite a large business. None of my associates had any access to leads, so that's how we got started. The demand for leads grew so fast that I had to focus on getting quality, affordable leads in ever increasing numbers.
