The rise in digital communications, and the use of technologies such as email in both personal and professional capacities, can blur the lines of etiquette. When it comes to the do's and don'ts of e-communication—especially when emailing with colleagues or clients—consider turning to an article shared by Jacquelyn Smith of Business Insider.
Smith's helpful email etiquette guide, titled, "17 Rules of Email Etiquette you Need to Know," was concocted with the help of Barbara Pachter, a career coach and published author on topics such as business etiquette. Many of the 17 rules Smith and Pachter lay down are generally common sense for modern email etiquette. Yet they serve as useful reminders.
For instance, most people know to use a professional email address (instead of something along the lines of labrat123@sciencerules.com). But lesser-known rules are also noted on the list, such as the belief that all emails should be replied to—even if you weren't the intended recipient. Pachter says that this often overlooked courtesy “serves as good email etiquette, especially if this person works in the same company or industry as you.”
