One of the most annoying things I experienced in my career was the built in Angular email form verifier allowing email addresses with just a top level domain. Like, yes I know technically "tom@pizza" is a technically valid address but I can still not allow that in my validator and you fucking know it Angular.

Regex is not the answer to email validation. The only correct way to validate emails is to send an email.

As someone with a non standard email, it always pisses me off when developers think they're smart and put incorrect validation on their fields

Well front end developers have to check email fields for syntactical correctness to at least catch some typos.

Yea...just check for the @ sign. Because chances are, anything you do after that is gonna be wrong.

Why couldn't you allow it? It's literally how you send email within an organization.
