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
If you want to find solutions online, stop using Google.
Sometimes I post stuff to my blog about things that I could not find a satisfying solution to and where I had to figure one out myself. I post those things because I want it to be discoverable by the next person who is searching for it.
I did a quick test, and my posts don’t show up anywhere on Google. I can find them via Kagi, DuckDuckGo, and even Bing. But Google doesn’t show my stuff, even when hitting specific keywords that only my post talks about. And if my site even shows up, it is only about +6 months after I posted.
Even tried their search console thing, it doesn’t report any issues with my site. So it must be the lack of ads, cookies, and AI generated content which makes Google suspicious of it.
So, If you are an engineer looking for solutions to your problems online, just stop using Google. It’s become so utterly useless, it’s ridiculous. Of course you will miss all the cool AI features and scam ads, but there’s always some drawbacks.
