The billionaire entrepreneur spends his days in and out of his inbox. He likes to sift through hundreds of emails a day, more than first person meetings.
“I get around 700 emails per day and manage everything using three phones (two Android and one iPhone)” Cuban said I wrote it Business insider, Ironically, by email. I would rather receive 700-1,000 emails than sitting in a long, boring meeting. ”
Cuba said Business Insider His day is “boring” and sends emails squirting around his morning Decaff coffee to bring his daughter to school. He then joins a workout session with Life Time Fitness before taking a second shower and returning to his inbox.
“I read and respond to emails. I work out. I read and respond to emails. I do some zooms. Then I read and respond to emails. Then I read and respond to emails. Then I read and respond to them.”

Cuban Productive Email Setup: AI Replying to you, No Holidays
Cuba is an email enthusiast and prefers the lines of communication over Slack, Texting and Calling. Cereal investors said Business Insider He has messages dating back to the 1990s, so he’s his favorite because he can search for emails in a few decades. He began sending emails about Compuserve (the company that acquired Cuba’s microsolutions business for $6 billion) in the 1980s, but still has a bunch of folders with former employee addresses.
The 66-year-old businessman thinks the communication format is more productive. Business transactions, employee communications, and media processing are requested “asynchronously” from all over the world. Email makes things easy to accomplish with his timeline. Plus, everyone has it in their back pocket.
“There are really no restrictions on the type or format of content. You can include it in your email or attach anything,” Cuba writes. “Everyone has an email. In 2025, you don’t know who isn’t… it’s fast. Especially now, there’s a Google car replies.”
But besides checking his inbox and responding to emails repeatedly throughout the day, there are also ways to email Cuban emails insane.
For 10% to 20% of his email, Cuban said he would use one of Gmail’s recommended responses to save time and brain power. He allows AI to write auto rupee from time to time. Or use the tool as a “typing hack” to save time by writing long responses, but stated, “usually I’m going to add a flavor somewhere.”
He also keeps using folders to organize his inboxes due to too many emails over the years.
Cuban says he never wants to hit Inbox Zero because he intentionally keeps reading some emails as reminders, but he aims to keep these below 20 messages. Sometimes he can lower that number to less than ten.
It is an ambitious goal that requires constant cleanup in his inbox, meaning Cuba will never take a break from his emails.
“I’m struggling to cut,” Cuba writes. “It’s faster to keep it out of the way.”
