Junk mail, forwards and commercial spam can be ignored but, your respond to a real message is obliged. Whether it is an invitation, meeting notice or just a hello from a friend. How fast should you respond? Within one to two days for personal messages and within twenty four hours for business e-mails, depending on it’s urgency. Instead of including all entire message that you have received, leave just enough to make it obvious what you are responding. If you are going to be away from your computer or smart phone, use a “out of office” or “vacation” feature which let the sender now that you are away until a certain date. Once back, respond promptly.
