While even small list can make you serious money, it is always better to have bigger list because that means more money. That's just a mailing list common sense. Now we come to the problem that all new online marketer face with - how to build strong, powerful and solid list of prospects? For many people that is a big problem since they don't know where to start and what to do.
But, there are answers and solutions for that. First of all, you should find some PLR (Private Label Rights) products that you can obtain for free, download and use as your own or to have rights to give them away. There are thousands of mailing list available PLR products in any niche you can think of. Just search for them on search engines and you should be able to find them in less than ten minutes.
When you have a product you can give away for free, you should register with some autoresponder service (there are many available autoresponder services online) and grab their autoresponder code that you will include on your website. You should build mailing list your website in the form of squeeze page (again use search engines to find out more about squeeze pages) where people will enter their name and e-mail address to be able to download your free e-book.
