Emails are a large part of the work that you will be completing. Emails should be answered in a timely and professional manner. A client or customer should not have to wait for days for you to respond to an email, nor should the email be informal and in poor taste. All emails that are sent out can be forwarded, printed or saved for a later date by the recipient. It is extremely important that all correspondence be professional, as there is no way to know in advance the potential reach of a single email.
