Most MLM Lead Companies offer Double Opt-in MLM Leads to help you build your downline. I would recommend ensuring that you are using a trusted MLM Lead Company that has been in business for a while. You want to make sure that the MLM Lead Company that you choose will stand behind their product and service.
You do have the option of creating your own double opt-in leads through an Auto-responder Leads System. Once you have set up an auto-responder account with a reputable service all you need to do is write some qualifying emails and load those into your auto-responder.
Once that is done go to your MLM Leads Company and order a few hundred Auto-Responder Leads. Your qualifying emails can be set up to remind your home business leads that they took a survey and asked to be contacted. Let me give you an example of what I mean.
