Because the program sets the value of DEFAULT_NUM_BINS to 24, a maximum of 24 users can be sent daily. May I ask what is the meaning of setting 24 here and what should be done for users who exceed 24?The relevant codes are as follows：

DEFAULT_NUM_BINS=24

num_bins = resolvers.DEFAULT_NUM_BINS
for bin in range(cls.num_bins):
    task_args = (
        site.id,
        serialize(target_date),
        day_offset,
        bin,
        override_recipient_email,
    )
    cls.log_info('Launching task with args = %r', task_args)
    cls().apply_async(
        task_args,
        retry=False,
    )
