Last month I got a .email domain with plans to become my primary email address, I like it because that gTLD clearly states the purpose, but after a month long test I have some doubts.
Lots of email validator around still are hard-coded, so any TLD equal to 3 characters seems to be almost automatically validated, while with something longer you have to get some luck.
Plus, some non-fluent in IT still does not recognize it as a TLD as most are accustomed with shorter TLD; as example last week a close friend asked if my domain .email was ending in .email.com or .email.net etc.
Buy since registration I hadn't any technical issues with mail servers, no email was rejected, nor any email was lost during the receive phase (I kindly asked to put in CC the new email address)
For those reasons I'm unsure about keeping it, or switching to a .xyz, the switch seems to have some advantages as being a 3 char domain... it seems to have also a growth greater than other gTLDs, and, as such, it should be more recognizable in the short term.
I'm unfamiliar with the value of a .xyz domain, there seems to be at least a million of .xyz domain registered, but is it really that popular, or it is just marketing?
Is it safe to go with xyz rather than any other gTLD for a personal (and future professional) email contact? Yes, .com is already registered, also the corresponding .eu and my country ccTLD...
