I just wanted to post this here because I want to help you all and hurt gen.xyz as much as possible. I had a .xyz domain through njal.la which I used to host jellyfin, homeassistant, and other basic things for friends and family. My domain recently became inaccessible without any notice. After a while of troubleshooting, I found that it had been reported to xyz as abuse, and they must have done zero investigation whatsoever before serverholding my domain. I thought about opening a ticket with xyz to get my domain back, but realized that I no longer wish to buy from some shitty company that will take down any site without warning. Bought a .com domain since they are somewhat reputable, and I would advise everyone here to never buy a .xyz domain. Angry rant over.
Most email providers will automatically put emails coming from .xyz to spam. I’d advise against using any “new TLDs”, if you can. But if you must, avoid those that are frequently used for spamming. A lot of spam detectors will already score your emails as suspicious just for the TLD.
See for example, https://github.com/apache/spamassassin/blob/trunk/rulesrc/sandbox/pds/20_ntld.cf
No wonder why some reported my mail fall into spam dispite I rarely sent any. God. I had it for almost 10 years already, and migrating would be painful.
