If you read the instructions at the top, you can put an address label on it too, just have to write in your email.
I just use one of those return address labels that get sent from insurance companies or questionable charities.
I have sent a few receipts that were a little past their send by date and they still honored them- I’m sure that they don’t want to piss off customers, especially since the rebate is just store credit and many people will go in because of their several dollar rebate and buy a lot more.
