You will be able to tell your followers of the good and bad points from a firsthand perspective, which will be appreciated by them. Even though you will have to spend some money and time initially, the money you earn later through the volume of sales will make it negligible.

Explain to them about your opt-in list and they will definitely be interested in getting their product promoted. All you have to do is to work out the percentage that you will get from each sale and carry on from there.

As you can see, by taking a few simple steps you can improve the power of the message you are sending out. By sending a compelling message you will increase the lure to buy. When that lure proves to be irresistible, your sales figures will improve drastically.
