.systems wasn't one of the most affordable new gTLDs used for spamming but a lot of mail sites blocked or at least increased "SPAM score" for most if not all new gTLDs. With .systems I would expect somewhat reduced inbox deliverability but with .icu, .xyz, .top, .live and similar, you can forget about egress email.
