Every time you contact a client you should provide them with a benefit for taking the time to talk with you, meet with you, or read your letter, fax or e- mail. Don't share your daily trials and tribulations - those are your issues, not your client's. Don't be long-winded. Don't spend time on unimportant details. Watch out for the opposite extreme - pulling a disappearing act.
Nothing annoys a client as much as hearing nothing.
No news is not always good news. If your client doesn't hear from you, their natural assumption will be that you're doing nothing. And if that's the case, then something is very wrong. Use your intuition Because every client is a little different, look for signals they might send that you are, or are not, in the right amount of contact. They are frequently too busy to talk with you.
