I completed my first e-mail newsletter for my legions of subscribers, all three of them. You can view it free of charge here: http://tinyurl.com/2763pzp.
Authors should consider sending an e-mail newsletter. They are an effective way to reach people who want to read you. Sure, Twitter and Facebook offer the same connections. But newsletters are engrossing and offer attractive formatting options.
There are free templates hanging out on the Interwebs. Download one and alter the HTML until you have a nice template. Then just fill in the blanks when it's time to send the next one.
