Rakuten sent me my Big Fat Check Cash Back

I saw and email from Paypal and I thought my transfers from ibotta and Upside were already deposited to Paypal. I noticed though that it has Rakuten on it and it says I just received a Big Fat Check Cash Back.

This Rakuten Cash Back will also go to my moomoo account.
