The next obvious Brazil email lists question for you might be, what is the best business model for you?
Because I believe that the list building model is the most lucrative, I am simply going to recommend that regardless of your product or products, you should be using the list building model for your entry point.
After that, unless you already have a catalogue based model set up, or have a specific desire to sell a selection of products that are best geared towards a catalogue setting, I believe that you should set up your entire line of products as a sales funnel.
Use a free product as your squeeze page entry, and then a low priced product as the entry point into the sales funnel itself. If you already have a selection of low priced products, consider promoting a rotating selection of the low priced products. Once your subscriber has purchased one of the lower priced products, opt him out of the low priced email list, and only send him higher priced products.
If you do not have a higher priced product, you need to create one. Once someone has made a single purchase with you, they have much more value to you as a customer purchasing higher priced products than they do purchasing additional lower priced products.
By the way: You Must Be CAN-SPAM Compliant
Because this is such a serious matter, and courts are repeatedly fining internet marketers for sending out unsolicited commercial email, I feel it is imperative to mention this again, before I begin to actually teach you how to create your list building campaign.
