Sebastian Galassi, 26, was a delivery rider in Florence, Italy, for the Spanish startup Glovo.
He died on October 1 after his moped collided with a Land Rover SUV while on shift for Glovo.
His family discovered an email the next day firing him, which Glovo claims was a mistake.
The following day, Galassi's family discovered an email informing Galassi that he had been fired from the company "for non-compliance with the terms and conditions" of his role.
A Glovo spokesperson told Insider: "We deeply regret the death of the delivery driver Sebastian Galassi as a result of a traffic accident in Florence, Italy.
