class InvalidEmail extends DomainException
{
  public static function becauseItDoesNotMatchEmailSpec(string $emailAddress): self
  {
    throw new self(sprintf('%s does not conform to a recognized e-mail address format'), $emailAddress);
  }
  
  public static function becauseTldIsNotAllowed(string $emailAddress): self
  {
    throw new self(sprintf('The tld of %s is not allowed'), $emailAddress);
  }
  
  public static function becauseItWasBanned(string $emailAddress, Date $onDate): self
  {
    throw new self(sprintf('The e-mail address %s was banned on %s and is not acceptable for the purposes of this amazing system we have here'), $emailAddress, $onDate->asString());
  }
}

Minor suggestion: return new self(...); and throw it at the site of the error, keeps stack traces a little shorter
