I have a .haus domain for personal use. I can send and receive email just fine, but I do run into a lot of apps that do some sort of misguided "validation" on the email address and reject .haus as an invalid domain. One retailer lets me use the .haus email address as a login, but once I log in and try to make a payment it requires me to enter a different "valid" email address to send the receipt to. It's very irritating.

I've been using a .info domain for email for, I don't know, 15-20 years. Maybe 3-4 times in those decades I've run into a service that won't let me sign up with my "invalid email". And once, I was locked out of my smart garage door opener app because a new version decided my already-registered email was now invalid for logins. Customer support kept telling me to just reset my password, but even the password reset form decided my email was invalid. A few months later, another new version of the app decided my email was valid again.

I have similar issues with my two main emails, which end with `.app` and `.sexy`. Both of these work fine, but validation will fail a lot of time (particularly for `.sexy`, but even for `.app`), forcing me to defer back to an unwieldy .com that I own.

I have a .co domain that gets rejected occasionally as well. Highly regret that domain choice since people often mistake it for .com.

I used to have a weird .red domain and I always found it awkward to tell people. So I ended up going with [e-mail] and literally no one has got it wrong or looked at me funny.

I had a .co domain, and it was a pain to spell it out to people. "It's like .com, but without m" and people usually got confused, or thought it was a typo and "fixed" it as .com.

I have a .dev domain now and everything seems to be running smoothly, plus it's +20% cheaper.
