If anyone looks at the email, it's not from you, only the fake name on it is that. Then the reply to is something very close to your account, but from a different service or with one letter changed, or from a different service. I got one from a friend last week, he's USguys96@ and the fake is USguyss96@ The last one before that the friend is ATT.com and the fake came from Gmail.

Basic point is, no one stole your email account, they probably didn't get into your mail and your account is not, probably not, hacked at all. It's just spoofed. Somewhere, somehow they got your address book.

And even if they did get into your account, all you need to do is change your password to lock them out. Then write to everyone and say, you are fine.

I did a search, here's the first one that came up. https://ist.mit.edu/news/gift-card-scam#:~:text=If%20you%20respond%2C%20usually%20they%20ask%20you%20to,an%20entire%20lab%20or%20one%20person%E2%80%99s%20direct%20reports.

"The scammer has just spoofed the email address that it appears to be coming from (often just changing the display name), not compromised any account."
