I put out a monthly, 2-sided newsletter. I found that the bigger I grew, it was a great way to communicate with my clients. I also use it to promote additional services and try to keep it light and informative. It's self-produced on a standard publishing computer program and while it's time intensive, my customers always comment on how much they like and look forward to reading it every month. It's a huge time committment every month but if I were to stop now, I think it would be missed. Anyone else use a newsletter? Care to share comments or ideas?
