If you don't receive an item purchased online from a private party it is mail fraud?

Mail fraud typically involves the use of the postal service to deceive someone for financial gain. If you purchase an item from a private party online and do not receive it, it could be considered mail fraud if the seller had no intention of delivering the item and used the mail to facilitate the scam. However, not all undelivered items constitute mail fraud; it may depend on the seller's intent and the specific circumstances of the transaction. It's advisable to report the issue to the platform used for the purchase and consider filing a complaint with appropriate authorities if fraud is suspected.
