That’s not the same as what parent comment was suggesting. You can’t send money to literally anyone using only an email address. You and the recipient still have to have regular bank accounts within the settlement system. The email address only serves as a more friendly identifier than the account number.
I should've been clearer: as long as the recipient has linked their email and/or mobile to their account (via PayID) settlement is instant and their email/mobile number can be used to address transfers
