"I saw an ad on Facebook that the Mega Millions jackpot was getting pretty high, so I got on my account and bought a ticket," Spears said. "A few days later, I was looking for a missing email from someone, so I checked the spam folder in my email account."
Spears said a message from the Michigan Lottery caught her eye.
"That's when I saw an email from the lottery saying I had won a prize. I couldn't believe what I was reading, so I logged in to my Lottery account to confirm the message in the email. It's all still so shocking to me that I really won $3 million," she said.
The winner said her prize money will allow her to plan an early retirement.
Spears said she has taken measures to prevent the same situation from occurring in the future.
"I definitely added the Michigan Lottery to my safe senders list just in case I ever get lucky enough to receive another email about a huge prize," Spears said.
