Hey I disagree here. I'm a real estate broker for some high profile clients. I will be the first to tell that there's a difference between ASAP and timely. If you respond to everything immediately then your entire day becomes one big multi-tasking disaster. The quality of your work and your sanity will surely suffer. And honestly I think responding to everything immediately causes burnout. You can block schedule hours in your day when you respond to email. The emails can wait I promise you.
