You can let affiliates know in any way that you wish to. This can include (but is not limited to) your email list, your own website, blogs, etc. If you are unsure of the best ways to find affiliates, you may want to ask other sellers how they promote their products. We are unable to provide specific advice on how to advertise, but we can point in the right direction for people who can help. One of the best places to find strategic information is on Warrior Forum (www.warriorforum.com). You will find years worth of experience there, and most users are more than happy to give advice to people just starting out.
