Note some services won't even recognize a subdomain email address as valid.

Really? Wouldn't that catch people with `.co.uk` or similar localized domains?

They use a regex such as /[a-z]+(\.[a-z]{2,3}){1,2}/

There’s a lot of bad email validation regexes floating around on the internet. If it’s an older service it may have been written before gTLDs.

I have an address that ends in .fyi and continue to encounter systems that refuse to accept it as a valid domain. It's really frustrating but at least I have a .com that I can enter into those and just forward it.

Technically .co.uk is a TLD [1], not a subdomain.

Yup, I've been rejected from a couple things, but it works for the vast majority
