Another strategy you can use is to start a mail lists. Mail lists are made up of people who chose to opt in to receive updates on your work, helpful hints, free stories, etc. Building this mail list will make it easier to promote your work when you are ready to sell it, especially since you are already marketing yourself.
The following are free services you can use to begin... Mail Chimp, IContact are two sources that I have found. Mail Chimp was recommended by Joanne McGonagle -The Tiniest Tiger. It is free, though they offer paid services as well. I Contact is not free, though it has a trial offer. I am going with Mail Chimp myself.
Make sure the people you send out mass mailings to have opted in to your mailing list. You do not want to be called a spammer.
