Elon Musk does not shy away from new ideas, and he's got users talking after hinting at something big.

It all began with a casual tweet from a user on X who wrote, "Xmail would be cool."

And, as expected, Musk replied nonchalantly: "Yeah, on the list of things to do."

Over the years, Musk's made a career out of shaking up industries, and with X turning into a one-stop shop for everything from social media to payments, adding an email feature could be the next big thing.
