Yes, that e-mail is too good to be true.

State Treasurer Deborah B. Goldberg’s office Friday warned Massachusetts residents about a scheme involving fraudulent e-mails referencing a Chicopee woman who last summer won a $758 million Powerball jackpot.

The messages are sent with Goldberg’s name on them, her office said, and falsely inform recipients of a sudden stroke of good luck.

The note says in part, “You have a donation from the former Massachusetts hospital worker, winner of the $758.7 million Powerball jackpot.’’

Except you don’t, according to state officials, who said the e-mails are not being sent by Goldberg or her office.

“It has come to our attention that emails using my name and likeness have been sent to residents across the state,’’ Goldberg said in the release. “Our goal is to ensure that no Massachusetts citizen is taken advantage of as part of this scam.’’

The former hospital worker referenced in the phishing e-mail is Mavis Wanczyk, a Chicopee woman who stepped forward last August to claim her prize as the winner of the largest Powerball jackpot awarded to a single player.

She announced at the time of her windfall that she was leaving her job at Mercy Medical Center in Springfield.

Scammers have invoked her name before.

Shortly after she won, Chicopee police said multiple social media accounts claiming to be associated with Wanczyk had sprouted up, offering strangers cash in exchange for personal information.

“We are well aware of many fake accounts being created on Twitter, Facebook, and Instagram stating they are Mavis Wanczyk and that following and answering private messages will result in you getting money,’’ Chicopee police said at the time in a statement.

“PLEASE do not fall for these scams. DO NOT give out any personal information to these accounts. Do not fall victim to a scammer by releasing ANY of your information.’’
