Smartphones have made e-mail accessible 24/7. But ask yourself: Are you getting more done, or just doing more? If you’ve begun to feel like a wheel-bound hamster, try these tips from Harvard Business Review:

• Reply by phone. Quick calls can often prevent dozens of e-mails. A five-minute chat is often more efficient than crafting a message that adequately explains the situation.

• Do not copy. If a message you’re sending requires a recipient’s attention, include that person in the “to” field; otherwise, leave them off entirely.

• Put down the smartphone. Crafting an e-mail on your mobile’s tiny keyboard can waste a lot of time. Wait until you’re at your desk or with your laptop or tablet. That way, you can craft a better response in less time.
