American billionaire and Shark Tank investor Mark Cuban has revealed that he avoids phone calls altogether. As reported by Fortune, in a TikTok video posted by Masterclass, Cuban said, “No, I don’t do calls. You know, I’ll engage with you via email, and trust me, I do this all the time. I’m really good at it.” He further explained that emails enable him to craft a more thoughtful responses and also helps him in preventing from forgetting details midst his bust schedule. “I’ll give you more comprehensive responses than if it was via phone,” he noted, adding that emails also provide a searchable record of conversations.Cuban’s stance echoes a broader generational trend. Many Gen Zers prefer email or text over calls, but for different reasons. A 2024 study found nearly a quarter of the generation avoids answering phone calls entirely, often due to telephobia — a form of phone anxiety that can trigger physical symptoms such as nausea, shaking, and difficulty concentrating.Talking to Business Insider, Billionaire Mark Cuban revealed that his daily routine is not at all exciting rather it’s quite boring. “I read and respond to emails," he wrote in an email. "I work out. I read and respond to emails. I do a couple Zooms. Then I read and respond to emails. Then I eat dinner. Then I read and respond to emails,” Cuban told BI.He revealed that his day starts with a decaf coffee and a cookie. He then takes her daughter to school and after that he works out at Life Time Fitness. Once done with the fitness regimen he again dives into his inbox. Despite his wealth, Cuban refuses to hire an assistant to manage his email, saying it would only “slow things down.”“I receive around 700 emails a day and use three phones (two Android and one iPhone) to manage everything. I'd rather get 700 to 1,000 emails than sit in long, boring meetings,” Cuban told BI.He emphasised that emails work for him because they come with searchable history. He also use Gmail’s auto-replies for 10–20% of messages. Cuban also mentioned that that in order to stay focused he keeps the unread emails under 20.Cuban rarely disconnects from email—even on vacation. “It’s faster to just get it out of the way,” he said. Only family events or emergencies prompt him to step away from his inbox for more than a few hours.While some may find his routine monotonous, Cuban sees it as a strategic advantage.
