(CNN) – A spam folder isn’t just junk mail.

Laura Spears of Oakland County, Michigan can attest to this, having recently spotted a $3 million lottery prize in her salary.

The lucky winner purchased a Mega Millions ticket on the Michigan Lottery website for the December 31, 2021 draw. She matched five numbers to win $1 million, plus she got the Megaplier to double her prize in three.

Spears, 55, told officials at Michigan Lottery. “A few days later, I was looking for a missing email from someone, so I checked the spam folder in my email account.”

“That’s when I saw an email from the lottery saying I won a prize. I couldn’t believe what I was reading, so I logged into my lottery account to confirm the email. Still everything is great! Shocked me that I already won $3 million!”

Spears, who took home her prize at the lottery headquarters last week, said she plans to share her winnings with family and retire early.

Of course, you’ll also check your spam folder often.

“I definitely added the Michigan Lottery to my list of safe senders in case I was lucky enough to get another great email,” Spears said.
