Answer 1

I think you would use a ScheduledExecutorService and call it like this.

ScheduledExecutorService exec = Executors.newScheduledThreadPool(amount);
for (int i = 0; i < amount; i++) {
    exec.schedule(yourMailSendingRunnable, delay, TimeUnit.MILLISECONDS);
}

You should replace amount, yourMailSendingRunnable and delay to account for your needs.
