And its hard to even pick a name that sound good when you say it like Pro-ton-mail is easy to pronounce, I can’t think of some good domain name like that to choose.

I did a 4 letters domain .me

That way it’s quick and easy to say, letters by letters dot me. Usually using your initials (generally 2 letters) + ISO 3166-1-alpha2 letters country code works well.

So if you are Fidel Castro from Cuba your domain would be FCCU.me
