As I have mentioned before, hard copy newsletters are still a good marketing tool. Another article that sets forth some good basic suggestions for newsletters by Paramjit Mahli appears in “Small Firm Business” newsletter.
Another approach to “newsletters” that I like for keeping in contact with clients is the one issue, one-page (two-sided if you must) law alert or advisory on a new case, recent legislation or regulatory changes. It has several benefits:

-it’s quick to put together and thus more timely,
-not delayed while waiting for others to contribute their articles,
-more likely to be read upon receipt, and
-creates more opportunities to make contact with clients, referral sources and prospects.
Remember, constant contact, contact, contact is basic to professional services marketing.
