Mailchimp seems to be a very popular e-mail newsletter service, and I can see why. It's playful, easy to use, and inexpensive, in fact, free up to a very large number of emails. I just wrangled my way around it and sent out my first-- July 2011-- newsletter, covering news about my books, forthcoming works, podcasts, videos, articles, events, and writing workshops. I also included a free 50+ page e-book of tips for creative writers.

P.S. I'm aiming to adhere to my own idea of best practices in sending newsletters. Read more about that here.
