I was looking at getting a short gTLD for a website I'm starting, but I'm wondering how well they're supported (meaning will DNS resolve, can people send me email, will I get rejected for using the address for account creation on sites, etc). The com/net/org/etc and ccTLD's I know are almost universally supported, but if I had example.whatever, how likely am I to run into issues?
Apart from a few sites like ticketmaster (not resolved) and discord (now resolved) not recognizing the TD I've had no major issues.
Your email reputation will likely be lower rated and likely be thrown in spam with major providers(Microsoft/Google) but that may also be because I am hosting my own email server.
