Here are three simple tactics to battling email overload. First use a telephone. “Quick calls can often eliminate dozens of emails,” HBR reminds us, and chatting briefly often take less time than crafting an adequate response. Second, don’t copy messages to people and tell your colleagues to do the same. Third, don’t try to tap-tap-tap replies to people on your smartphone. Wait to do it when you’re at your desk where it takes less time to whip out a reply.
