Making commissions is the goal of affiliate marketers. Marketers need a mailing list to be able to make a comfortable income. Building your list will mailing list be the best spent time of your affiliate venture. Building a list of ready to buy prospects will be the most rewarding thing you can accomplish. You can literally make hundreds or thousands in just a few hours of your mailing.
But, do you realize that maybe 90% of affiliate marketers are not making money. Even with relatively large list. This could be do to a number of reasons but, myself I would say lack of trust is the number one reason. Sometimes things get off to a great mailing list start and you make one bad move and promote a product that just wasn't that great. Your list members lose faith in you. So please by all means try a product before you make your recommendation or search for positive reviews about it.
Then again you get all the hype on the next greatest product launch and you want to be one of the first to promote it. Well, you can take your chances or if you know the author is well respected for his superior products, you should not have a mailing list problem. Keeping the trust of your list is your main objective. Trying to sell them an inferior product. could cost you a lot of money.
