Should I keep payment confirmation emails from PayPal?

As is well known, PayPal sends a confirmation email for every payment. Do you have to keep them at all with monthly payments like Spotify, Netflix and stuff like that? Because a lot comes together in the long run. I'm just unsure, if something should happen, you have a "receipt" that you have paid for it. But maybe it's unnecessary?

I thank you in advance!

You don't need to keep every mail. If you were you, I would download and archive the monthly list of PayPal activities from your PayPal account.
