i got an email saying someone bought something on my account but i found it in spam... is it real or fake?

If you're talking about iTunes, you can review the purchase history on your account by following the directions in the link below.

See your purchase history in the iTunes Store on a Mac or PC - Apple Support

I hope this answers your question.

Best regards,

Austin

If the e-mail addresses you with Dear Customer or something similar then it's spam.

Delete and ignore.

Apple e-mail addresses you with your full name.
