You can try with:

^[\w.-]+@[A-Za-z0-9]+([-]?[A-Za-z0-9]+)+([\.][A-Za-z0-9]+([-]?[A-Za-z0-9]+)+)+$

The above regex is updated here : https://regex101.com/r/7P4XWM/3

Hope it helps :)

You can try with that regex:

^[\w-_\.]+@\w+(-\w+)*(\.\w+(-\w+)*)+$

With that, the following condition is not fulfilled, though:

  • Each subdomain must have at least 2 characters.
