A successful internet marketer is patient and knows that the most important thing to get from a potential customer is their name and email. Everything else is secondary, but you need to get those two things. You also need to make sure that you are getting targeted leads for your niche. This means that the emails that you are able to get should come from people who are showing interest in what you have to offer. You can contact Hotmail support if you are using Hotmail for this.
A good way to start collecting emails from people is to offer a free guide or eBook on something that is related to your niche. For example, if you want to sell gardening products as an affiliate marketer, you should offer a free guide on how to keep your garden equipment clean. The only requirement to get your guide is that they give you their name and email. This is going to allow you to know that each person that subscribes to your newsletter with their name and email is going to be a targeted potential buyer of gardening tools.
