Mark Cuban says the rise of AI-generated cold emails has gotten so overwhelming that he is now fighting back with AI of his own.
Speaking on the live-streamed tech show TBPN on Thursday, the billionaire investor said he recently bought a Mac Mini to help manage the growing flood of inbound messages.
“I do what everybody else does. I bought a Mac Mini,” Cuban said.
Beyond AI-generated emails, he said the issue is unwanted email subscriptions.
“It’s not even like the cold emails because that’s pretty obvious,” Cuban said. “It’s people subscribing me to shit.”
His fix, he said, is to use AI to automate the cleanup.
Cuban said he is training systems to take advantage of Gmail’s built-in unsubscribe button, effectively creating a loop where AI filters out AI-generated noise.
“You just got to train it to hit the unsubscribe button,” he said. “Then, I just review it and all that shit, so it’s still a work in progress, but at least I have a path.”
Cuban didn’t immediately respond to Business Insider’s request for comments.
A ‘trial and error phase’
The approach reflects a broader shift in how executives are using AI to manage their inboxes.
LinkedIn CEO Ryan Roslansky has said he uses Microsoft’s Copilot for “almost every” high-stakes message, and executives across industries, from tech to retail, recently told Business Insider’s Ana Altchek that they rely on AI for day-to-day communications and reviewing documents.
Cuban framed the current moment as a trial-and-error phase, where people are testing what works and what doesn’t.
“We’re in that trial and error phase where people are like, ‘We’re going to try it, see what happens,'” he said, adding that response rates will likely fall as more AI-generated messages flood inboxes.
“Then they’ll get bored, and then it’ll drop off,” he added.
