Cristian Rennella is really good at email. He responds to my messages within minutes, an especially quick turnaround for a CEO. (Rennella co-founded the South American travel comparison site, El Mejor Trato.)
His secret: He banned email at his company. Without clutter and requests from colleagues, he gets less than five emails per day. With so little to do in there, it doesn't take him long to get to my communiques.
