code: def send_many(kwargs_list):
      
      emails = []
      for kwargs in kwargs_list:
          emails.append(send(commit=False, **kwargs))
      Email.objects.bulk_create(emails)
docs: Similar to mail.send(), but this function accepts a list of kwargs.
      Internally, it uses Django's bulk_create command for efficiency reasons.
      Currently send_many() can't be used to send emails with priority = 'now'.
