Everywhere I go look at promotional tools I keep seeing email lists or newsletters as one of the best ones to have. However, I don't see how one could create such a thing without becoming spammy. I'm sure there are ways to do it without doing so, but I guess as of now most people that I have emails for are friends, family, and people I know through work. So it seems kind of strange to target my style of stories towards people I know most likely wouldn't read my style of writing. I know there are services that help target people that would be in your audience, but I wouldn't even know where to start. Have any of you heard anything about building email lists or if these are valuable tools? I imagine for a bigger writer this would be good, but for a relative unknown it might be a tough climb.
