It's very useful to have a free newsletter to build up your mailing list so you can offer articles , services and affiliate links that can help people and grow your list.
But what is the best way how to build your list? By giving away something for free AND that has value you can get subscribers.
I'm a licensed social worker and have written a 41 page ebook of famous quotes with questions to ponder. You can have full resell and master resell rights to this ebook and give it away or sell it to your customers. It is not another "how to make 1000 a week " ebooks but has universal value since everyone loves quotes. Stop by and see more about it. I will customize the links with your clickbank id and the bottom paragraph can be written by you and I'll put it in and link it to your site. Everyone who you sell this to or give it to will now have YOUR links in the ebook and be passing it on to others.
