Valid Email Format Rules

  • Must contain exactly one @ symbol
  • Local part (before @) can contain letters, numbers, and some special characters
  • Domain must have at least one dot with a valid TLD
  • No spaces allowed anywhere in the address
  • Cannot start or end with a dot

Note: This validates the email format only. It cannot verify if the email address actually exists or can receive mail.
