Validating email values using a calculated column?

Hello,

I have a dataset taken from our customer database that contains a field called "email".

What I want to do in the Power Query Editor is to create a calculated column that checks if the value in that email field is valid (in terms of syntax) ie the value follows the structure of: "name"@"domain"."extension"

I stumbled across some code on stack overflow which is similar to what I am after but this code requires the email address text to be manually entered. I just want it to take the text from the email field and to run that through the validation process and then the output should either be "Valid" or "Invalid".

let
    IsValidEmail = (input as text) =>
    let
        name = Text.BeforeDelimiter(input,"@",{0,RelativePosition.FromEnd}),
        ext = Text.AfterDelimiter(input,".",{0,RelativePosition.FromEnd}),
        domain = Text.BetweenDelimiters(input,name&"@","."&ext),
        return =
            Text.Length(name) > 0 and
            Text.Length(domain) > 0 and
            Text.Length(ext) > 1 and Text.Length(ext) < 6 and
            name = Text.Select(name, {"a".."z","A".."Z","0".."9","_","-","."}) and
            domain = Text.Select(domain, {"a".."z","A".."Z","0".."9","_","-","."}) and
            ext = Text.Select(ext, {"a".."z","A".."Z"})
    in
        return
in
    IsValidEmail

Can anyone provide the correct code please?

Cheers
