Look around your office for ways email can result in cost savings. Send it by email instead. Making an email version available will save printing and postage costs. Signing up for email newsletters can get you information commonly copied and passed around in law firms. Sending the URL of an article by email saves the cost of copying and distributing the article.
Many users have a full-time Internet email connection and expect an instant response.
You need to keep that in mind. I've always tried to acknowledge and respond to all well-intentioned, unsolicited personal email. If you put your or your firm's email address on a Web site, advertisement or brochure, you must make sure that any email sent to you is answered in a timely fashion. Mind your Netiquette. Some are common sense and all are directed at imposing a set of good manners or etiquette on email usage.
